One thing that is important and was only mentioned once above (but I feel needs restatement) is the shutter adjust on the III -- I'm not sure if you can do it without cocking the shutter first. I don't know if that's just because it doesn't really line up with anything, or whether it can damage the shutter mechanism (I recall reading that somewhere, don't know if it's true). That and the film leader crap is really what bothers me most about my IIIc, but I still love using it and it's taken some great pictures of mine. They're great fun if you're willing to put up with a bit of prissy nature, like dating a fun and beautiful but high-maintenance girl.
