I just picked one of these up on Ebay this week and it looks a really nice camera. Tiny and very cleverly put together.
First impressions are pretty good. The shutter makes the wierdest noise though -- like a high-speed crunching sound. However, I put a film in it today and walked round the house/garden firing off frames and the roll, once developed, came out fine -- all the shots look properly exposed including the ones using the flash sync so it doesn't seem like the shutter noise is a sign of any malfunction.
The big viewfinder and the film loading system are particularly nice and the short base rangefinder seems easy enough to focus with.
Anyone else tried one of these?
