I have a bit of Soviet glass in my Arsenal (pun intended.)
Much of it is L39 mount as I also use a couple of FSU rangefinders. Namely the FED-3a and the Zorki-4K.
L39 Glass
(1976) LSOZ Jupiter 8 50/2.0
(1973) LSOZ Jupiter 11 135/4.0
(1959) KMZ Jupiter 12 35/2.8
(1963) FED Industar 26 50/2.8
(19??) FED Industar 61L/Z
M42 Glass
(1978) Helios 44-2 50/2.0
K-mount
(2006) LSOZ Zenitar MC 16/2.8
Most of my soviet glass is second hand excepting the Zenitar. One thing I can say is that all of these lenses provide me with superb images. The Jupiter-8 50mm is amazing as is the the Jupiter-12 35mm. This is hardly surprising though as they are almost identical copies of 1930s Zeiss designs.
Some people look down on soviet glass as being inferior and whilst I can see their point to a certain extent, all I can say is try it. You'll be surprised at how nice some of this stuff is.

Above image shot with a Samsung GX-1L and Zenitar MC 16/2.8. This image is at an equivalent focal length of around 24mm and does not show the fisheye distortion of the first image.
.... and here is the fabled Zenitar MC 16/2.8 itself. Be careful with this one as the front-element protrudes a little. Also be careful not to lose the front cap as it can't be replaced. My is floating somewhere in the North Sea at the moment
