I found my first rangefinder with manual controls at a pawn shop - a Konica Auto S2. It still had its original black case with Konica label on the front, and the body was pretty clean.

The controls are pretty simple - focus, ISO, shutter speed and aperture are all on the lens. The frame lines inside the viewfinder shift with the focus, which is a nice touch. For a '60's rangefinder, the viewfinder is still pretty bright, and the center patch is still visible for focus in a contrasting yellow color.

I ran a roll of Kodak Gold 200 though the camera. The film expired in 2002 and it's been waiting patiently in the fridge to be shot. I got some nice colors and stills out of the camera - it was worth the purchase and time spent to use it.
