At the price, I would not buy a Vixen LV without having tried it out myself along with the other options. From what I've read on CN, the LVs seem to be regarded as okay but not exactly the best value EPs.
I agree with Geoff's comments: good set of plossls in the 9-15mm range + good barlow make for a nice planetary set. If you don't mind a 45deg FOV then orthos + barlow will do very well too. I'm very happy with the orthos, plossls + barlow I own at the moment, as per my signature.
Still waiting for Asimov to comment on his review about the ED-2 planetary eyepiece
(which is supposed to be some sort of clone of the LV but has a wider field of view). Asi, you seem to be for the LV. What's your opinion of the ED-2 now, after having befriended the LV?
