I keep coming back to my Olympus XA for street photography. Rugged, very small, and takes sharp pictures (although it will vignette slightly at its largest aperture). It's an aperture-priority automatic, which sets it apart from some of the older rangefinders which tend to be shutter-priority. It doesn't have full manual but I've found the meter hard to fool. If the camera has a weak spot, it's the view finder. I find the meter and focus patch a bit hard to see, but I wear glasses which doesn't help matters. To me they are small issues since I tend pre-meter and range focus when street shooting. Good luck with your search.
