Lots of information on Russian and other MF lenses at www.mflenses.com
Some of those which I've tried:
Mir-1v 37mm f2.8 - a Zeiss Flektogon copy, pretty decent, nice bokeh (prefer it to the Super-Takumar 35/3.5)
Helios-44-2 58mm f2 - a Zeiss Biotar copy, also nice bokeh due to the nearly-circular diaphragm, a good "portrait" lens on crop DSLR
Jupiter-9 85mm f2 - a Zeiss Sonnar copy. I don't like the swirly bokeh wide-open but others do. quite soft wide-open (no need for vaseline on a filter) but sharpens up nicely at f/4
Jupiter-37AM 135mm f3.5 - a Zeiss Sonnar copy. I think I like it better than my Zeiss Jena 135mm f3.5! (it has nicer bokeh due to the full-manual aperture and circular iris)
now for one I haven't tried...
Helios-40-2 85mm f1.5 - quite large and expensive for a Russian lens.. probably the most expensive Russian lens. Better bokeh than the Jupiter-9 but the J-9 is way cheaper.
