There's still tons of milage to be had on cold-war era Prakticas. The one that I have is as old as my dad, the meter is accurate (and not stopdown metering!), the shutter is accurate, it takes a 625 battery (not a mercury battery) and the thing is damn near bulletproof.

I don't take mine out often since I got a Spotmatic but that's mostly because the Praktica was my very first camera and I'd feel awful if I lost it.
