I am basically in love with my Mamiya C3. I have a picture or two on the board about it and how the outermost bellows was ripped, so I patched the thing with duct tape and light blocking curtain fabric underneath that. The bellows on mine fold all wrong on the outside, but on the inside it's fine. The lenses are clear with just a few cleaning marks, and take a really nice, sharp picture.
Basically, pry it out of my cold, dead hands if you can.
I should actually mention that the lens I have on the camera is likely a later issue than the camera itself. It's a blue dot.
