Well you live in the right place to get bargain ex-Soviet cameras I remember some of my friends in the 1970's getting superb results from the Zorki 4's and the Kievs and their surprisingly good Jupiter lenses.

Just before Christmas I picked up a near mint Zorki C (Cyrillic markings) for 2 ($3.20/2.4- euros) and I really want a nice Jupiter lens for it, not the later black version.

The other Soviet era camera I find fascinating is the Zenit C, it's ironic that modern Cosina made rangefinder cameras (Bessa, Zeiss Ikon, Epson digital etc) are based on a Cosina SLR minus the mirror box. The Zenit C is a Leica copy with a mirror box added
