I'm waiting for them to be back in stock. For us Europeans they are backordered until the end of January.
They are almost the same as the Stratus except for the coatings and some camera adapters and stuff like that. For as far as I know they are slightly better then the Stratus but not by much. So spending 80 or 100 dollars more on a Hyperion sounds a bit to silly to me.
Here is a comparison between the Vixen LVW, Orion Stratus and Baader Hyperion. I’ve translated it for you to English with Babelfish

When in May 2005 this eyepiece row was announced, the similarity with briefly before the published eyepieces of the Orion Stratus row was indeterminable. This applied both to the shape of the housing and outward details, and to the announced structure of lens. After by the company Baader the complete hyperion pallet was put to me to the test at the disposal, this impression was confirmed, and like that it is meaningful to include the realizations from the experiences with the Orion Stratus into this empiric report with. Already at first sight itself Baader Hyperion and Orion Stratus are very similar, but evenly already at first sight not directly. The eyepieces are based however on the same structure of lens, as the company confirmed Baader. The Baader Hyperion is supplied in a sturdy sticking box, together with a soft pouch from imitation leather. Zuoberst in the packing is equal an additional eyepiece cover. This is one the small and thought out details that of hyperion. There is an eyepiece cover, which fits with turned down eyecup and a further, which on the folded up eyecup fits. As eyeglass wearers one can lock and away-pack thus the eyepiece also with turned down eyecup, which saves annoying handles with the eyepiece change. Also the further form of the Hyperion is durchdacht. As the Stratus can it be used in a 2"excerpt. While however the two tariff wedging is possible with the Stratus only on a very narrow ring, from which some clamping screw meets only the edge, has the Hyperion here a broad ring and even a safeguard groove. The safeguard groove gives it naturally also at the 1.25"connector socket, unfortunately unnecessarily deeply entrenched. Lately repeatedly problems with locking rings and safeguard groove one discussed. The safeguard slots with hyperion are broadly enough, in order to let also a locking ring dive into it. Particularly after in my circle of acquaintances two accidents with expensive equipment to me admits became, which would have been prevented surely by a safeguard groove, I remained with the endorsement of these safeguard slots. The total loss of a Zeiss Bino is my opinion after meaningfully enough. With direct comparison with the Stratus it is noticeable that eyepieces of same focal length are of various sizes. An exact view shows then that the field lens lies with some hyperion further down in the connector socket, as with the Stratus counterparts. After information of Baader this is to make the Hyperion usable with devices with little baking focus, in particular at some Spektiven. Since the Hyperion sits many more deeply in the 2"wedging, the 1.25" connector socket was also somewhat shortened, so that the eyepiece does not touch down on a zenith mirror. Nevertheless one should look first times whether also with the own zenith mirror like that is. Between that a further ring from silicone rubber is handy reinforcing and the eyecup from soft silicone rubber. Among them one finds a connecting thread for Baader "SP54" to photo adapter. If one takes the rubber eyecup off, which goes very easily, then one finds a M43 thread which fits some video cameras (e.g. Panasonic). To this thread also a T2-Uebergangsring can be screwed, which makes eyepiece projection possible with a mirror reflex camera. Suitably the "SP54"-Gewinde Baader offers adapter rings for usual digital cameras and also on T2. By these connection types the eyepiece can be begun nearly at each camera for projection. Particularly with the afokalen projection at a digital camera with firm objective the "SP54" connection is interesting, since the adapter ring ensures the smallest possible distance between eyepiece and objective and thus for a good illuminating of the display format provides. The adapter rings are at present available for very favorable 10 euro. The T2-Adapter ensures with additional extension rings then for the possibility of the eyepiece projection with mirror reflex cameras. As a result of the screw connection with the eyepiece a very much weight-saving and also stable construction arises. It depends natural thereby also on the okularklemmung, which should become stable however with heavy cameras at least in 2"a wedging enough. Also the centring of eyepiece and objective is so automatically ensured to each other. A further detail that of hyperion should be the usefulness of a second focal length. In addition the 1.25"connector socket with the Barlow element contained in it is unscrewed. The eyepiece is then in 2"wedgable and the thread of the unscrewed part functioned now as filter thread, so that thus also 2" filters are usable. Unfortunately the eyepieces screwed themselves thereby also gladly in the wrong place apart. Times it was the chromium-plated connector socket, which separated from the extension ring on 2", times went the eyepiece in the center apart. Particularly in the first case is to be found verflixt difficult it, a packing, in order to out-get the ring. In the future these threads with an adhesive become secured, so that the screw connection separates only, where it is intended. The use might be small meanwhile also for most star friends, because the Barlow element is taken into consideration into the function of the optical Design, so that particularly the edge illustration worsens. The observations should show, with which telescope types this option would be meaningfully applicable. Another idea for the change of the focal length is substantially more promising. A star friend came on the thought to screw in 2"filters directly between Barlow and eyepiece upper section. He noticed an easily stronger enlargement, which led to the idea, to shorten the focal length of the eyepiece by several empty filter versions as the distance between the lenses was increased. Warscheinlich are offered shortly for it even suitable verlaengerungshuelsen by Baader. In addition, the processing of the eyepieces is so far correct, corresponds the preisklasse. Like that the density of the filter thread was not particularly good in the 1.25"connector socket, because the used mattlack became not everywhere correctly matte and showed shining places. The lens locking rings are only black anodized and shine, while one would rather find a black mattlack naturally also here. The interior density precipitates somewhat differently. Here are it shown a few brightly shining rings, particularly with the long focal lengths, which are to be led back my estimate after on the again not correctly matte lacquer to internal screens and in the connector socket. On request it was communicated to me that within the range of the 2"filter thread a special sticking lacquer was used, which was to bind penetrating dust particle. The lacquer is to lie also outside of the path of rays, so that after-paint nothing to bring and only the function of the sticking lacquer would paralyze. The lens edges are however properly blackened, but like already with the Stratus also here a thin, bright line at the edge of the remuneration is noticeable. This would have no role however outside of the path of rays to lie and should therefore to play. As last exterior detail would be to be called the inscription. It is sufficiently large, yet one needs in the dark a while, before one found the focal length, because this number in character size does not stand out against the further letters. The eyepiece focal lengths are to be differentiated also by a colored anodized ring, but with red light that does not function naturally. As already mentions, the structure of lens that of hyperion is identical to that the Stratus. The manufacturer Baader stresses the use of a "phantom Group" remuneration for hyperion. The remuneration colors are different actually and on the "group photos" are noticeable those of hyperion as those eyepieces with the weakest reflexes. Since these pictures taken up under diagonal beam of light are however not meaningful, had to be compared with the observations carefully. In order to compare the structure of lens of the eyepieces, the eyepiece rows in the focal lengths 21mm, 13mm, 5mm and 3,5mm were compared directly with each other. The eyepieces were fastened and photographed in addition in same position to the camera, whereby as a result of the different size of Stratus and Hyperion however easy differences arose.
