I bought a Rollei 35S from KEH back in 1990, that I had to return to them twice for repairs. The focus ring wasn't engaged with the lens, even though the camera was listed as being very good. It was spotless otherwise, just wouldn't focus. I sent it back asap, they said the fixed it, but when I got it back it looked like nothing had been done. So, back it went & they fixed it again and it's been fine ever since, but it took me about 2 weeks to get this straightened out. Could have been a fluke, I dunno, but I haven't dealt with them since. About the only mail order place I've used has been Calumet, which isn't always the cheapest place, but you can get great customer service through them & the folks on the other end of the line know what they're talking about too.
