FWIW I have just bought (used) a Vixen 140mm NA140SS 'Neo achromat'. See this thread, http://tinyurl.com/ll6fhmu , in this forum for more information.
This is kind of a poor man's Televue in a way. It has an f11'ish (don't know for sure) achromatic objective and a focal reducer in the rear (built in) that brings the optical train down to f5.7. From a visual optical performance perspective it has many of the characteristics of a longer fl achromat but in a smaller package.
I honest did not chose this scope because I felt it was the best choice for me. I have become convinced that 'the best choice' for me is right now indeterminate. I wouldn't know it if I saw it (or in the case of a 175mm AP Starfire couldn't afford it). And this (used) scope was a very good price and I think that I can recover my investment if/when I decide to experiment.
Scope is (literally) in the mail.
A short first light review can be found here (Refractor forum).
