Thank you David, very useful information on what to look for when buying a camera. The giii I bought knowing it had a sticky shutter. The aperture blades are clean but the shutter blades are not. No problem as a friend has the tools to remove the ring holding in the front element. I'm going in that way and using some ronsonol to clean up the shutter.
Sorry for the confusion over "beater". I meant merely a rangefinder that was well built and could take some abuse. Not that I plan on abusing it mind you but things happen.
I have an XA on its way to me. I'll snag a RC or RD as the chance arises.
