Just wanted to bring some closure here. I finally bought a 'voks, with a custom CV/Gate mod, in very good condition from a member here. Serial says 1982/64 so I guess this means it's a very early model! It only took me 18 months from the original GAS attack from hearing Jexus' demos!

I would describe the sound as somewhere between the 70's Moogs(with less bass) and an exaggeration of the distortedness of the Korg35 filter in the MS10 and early MS20's. Contrary to its reputation, it's quite capable of sounding "pretty
", at least until you turn up the resonance.
If it really is true the sound from model to model can be quite different, I feel fortunate to have one that sounds exactly like I had hoped.
There are some disappointing things about it:
1) The so-called Filter FM isn't enough to do much more than detune VCO1 a bit, and there's no LF mode for VCO2
2) You get 2 envelopes but no Envelope Pitch mod or hard sync - imagine how brutal this could sound with a hard-sync sweep!
3) No pitch or mod wheels, so no simultaneous VCO vibrato from the panel - CV/Gate allows for it though
4) Volume, cutoff and resonance pots need cleaning - no suprise if it's nearly 27 years old
5) Keys action is soft and mushy, although seems to be responsive enough
6) No pulsewidth mod, but not too worried about it
7) Tuning trimpots on this model are flaky - if it gets moved, you may have to retune it
That's it though. It basically kicks ass.
My only real concern at this point is finding a tech in the States that could work on it, should it need it. Cross-referencing soviet to U.S. part numbers alone is bound to be a pain in the ass, let alone failure of any irreplaceable parts. It's definately worth the risk.

Here's a photo of it, now in my rig above my Jupe:
I don't have any recordings yet, but if anyone is interested, I'll make some sounds. Thought I might start with OJambo's advice from a while back and try out some drum sounds with just the noise and filter.
