Phil, I would suggest you check with sellers of actual stock on hand. Many of them show a waiting list or scheduled delivery when in fact they will have to wait for the new version due out later this year.
Depending on what scope you will be using, you will also need to consider which Glass Path Compensator you require. The glass path compensators not only shorten the required back focus but also correct for spherical aberration the system would otherwise induce in refractors. The GPC for Newts is different and increases the effective focal length of the scope by either 1.7x, 1.8x or 2.0x which has a dramatic effect on the true field of view you will be able to achieve with a scope.
I use the Televue Binovue with the Baader 1.25xGPC even though I can reach focus without it. This makes my TOA130 effective a 130mm @ 1250mm.
Lunar and planetary views with binoviewers are excellent. I don't use them for DSOs due to the fact binoviewers will dim the image. Binoviewers also reduce eye fatigue and the effect of floaters etc.
