As a possible alternative, it might be worth considering the OM-4. It's actually an SLR but a similar size to a rangefinder. Very nice weight, good features. They have the odd feeling of being the mix of a small, high quality manual camera but with some advanced features. Manual split and shimmer-image focus, spot metering, highlight or shadow metering, DOF preview. With an optional motor drive, 5fps. The build quality feels really good - made from die-cast aluminium with titanium top and bottom plates
But the best thing about them is the lenses. Zuico .... fast sharp and contrasty.
The quality of image produced is outstanding. Seem to be selling second hand around $300. Perhaps worth a look .
Robert Jaques here at apug has had one for many years. He could tell more about it .... I know he loves that camera.
