I'm interested in getting a bottom-loader and some LTM lenses, particularly that summitar and summicron. Now many of these bottom loaders are probably running slow and the lenses hazed up. It might* be cheaper and overall a better idea to just get any decent shaped body/lens and have them CLA'd. 1. The go-to people seem to be Youxin, Sherry, and DAG. Maybe a few others but they spring to mine. I haven't shopped around but Youxin's prices seem fair and his reputation pretty good: $120 for a bottom loader CLA and $50 for a cleaning. How are the rates of Sherry and DAG, somewhat similar? DAG seems to have the best reputation, so I'd expect 50%-100% more. When I have the lens/camera at hand, I'll give them a call and shop around a bit. 2. I wouldn't get a lens that is heavily scratched, has fungus, or excessive dirt, but it's safe to get one with a stiff aperture and/or light haze, right? I'm especially concerned because of Leica's soft coatings.
