Ugh, sorry you're having such bad luck with it! If all else fails, keep the lens on it (if you got it with one), and get yourself another camera body that accepts M42 screwmount lenses. They can be rather inexpensive. Besides the TL-Electro, Pentax Spotmatics and various Zenit cameras accept the same M42 lenses. It's no ideal camera, but I got a Zenit ET from eBay a while back for $7 and change, shipping included!
