I lived in Poland and it is true that for 50-100 PLN you can get FSU rangefinder with 50mm lens. My experience: zorki 4 sometimes eats film, kiev sometimes shutter does not work. Lenses are very good. For same money on allegro site you can get some olympus rangefinder like mju or RC series. You can not change lenses, but it is much more user friendly and less chance that you get semi functional example.
@desertratt: comment about UK - Mustafa was for sure joking , no real racism was there.
