for 50 dollars you can get a choice of, for what i know. all much realiable in tolerances, better assembled etc. etc. then any soviet camera on earth.
Only thing really referred as "very good" in soviet camera world are the legendary bags in "true soviet jak", and of course many lenses, if you get a well assembled one.
Ricoh and other brands as well produced very good SLR in K mount baionet way more reliable and actually as affordable as russian ones...
imho, of course
