I have the 8, 13 and 21mm hyperions and find them very good but I recently upgraded to a 27 mm panoptic, 16 and 9mm Naglers and have not looked back. I still have the hyperions though which I use on my sct for public viewing. I bought mine from Telescope Service in Munich for 100 euro each. Might be worth checking what their price is now as the Euro is in the gutter at the moment against the $. TS are great to deal with.

Edit
Just checked. 104 euro each but this includes 19% VAT which you won't have to pay outside of the EU. Give Patrick an email at TS and get a deal. Great company to deal with.
