I had a Canon 110 ED 20 which made great images, had a rangefinder for focus, and was a fun camera to shoot, WHEN IT WORKED. I bought it off the auction site, and it was great for a while, then one day a spring dropped out of it and for the life of me I couldn't find out where it had fallen out of. Well from then on out, it would work as normal and then right in the middle of a roll, it would seize up, and there was nothing I could do to un-stick it. Then it would sit on the shelf for a few months and suddenly it was working fine again, until again it would suddenly freeze up. Very frustrating. But if you can find a good one, great camera.
Best,
