I've often thought about one (or a TAL KCT)....but was always prevented by one thing:
Performance comparable to a standard C8 or M8, but for a higher price.
Hi, hi ... I know what you mean, but I can´t agree ...
I bought my 10" Klevtsov (a new one and with quite good optics) directly in Russia and payed in total 1.900€ (all expenses paid) - about the same (or a little cheaper) compared with 9-11" SC´s in 2010.
I think the real bargain you´d got with Klevtsov-type telescope are some additional advantages. But they are only "advantages" if you require them, otherwise they are only gimmicks, nice but needless.
* The quite fast thermal balance - but only if its not permanently mounted outside.
* The sturdy tube and firm collimation - but only if you have to transport the tube quite often.
* The loss of dew problems - but only if you live in areas the dew point is critical.
* The compact design - but only if your mount needs such a design, or you have to store the telescope afterwards.
BUT - if you are in a situation (by the way: that´s my situation) - you´re driving to observation places by car, with your telescope stored inside the house and with big day-night temperature gradients (in Central Europe) and using a CEM60 mount with this 15-16kg payload, it´s definitely one of the most suitable telescopes I ever owned.
OF COURSE - I own a 7" STF Maksutov too (better optics) and I´m doing the better planetary observations with the Mirage, but I have to wait twice the time for thermal balancing, have to stop observation 60-90 minutes earlier due to dew at the Maksutov lens and have to collimate the Mirage regularly.
SO - what´s the better telescope? No decision making (in general) possible. Sometimes the Klevtsov, sometimes the Mirage, sometimes my APOLAR ...
