I have a Petri Color Corrected f1.9 with the moving frame lines. It has an excellent lens and terrific ergonomics. They tend to be a bit fragile, though... it took me several tries to find a good one. It has a fixed 45mm lens.
The Minolta HiMatic 7s also has moving frame lines, but I think it also moves the image. Also a fixed 45mm lens (f1.8?). The 7s is one of the later HiMatics, and not as expensive as some, but it is still in the larger body. Very good meter and also a good lens.
Both were available with conversion lenses to give a wide (35mm) and tele (85mm) f3.5 or so... I don't ever use those, though I have them.
Both are also awesome for "traditional street shooting".
Some of the Mamiya twin lens cameras have a little red line that moves down the side of the viewfinder, telling you where the top of the image will be based on focus distance. It's really slick. They also have bellows to enable fairly close focusing.
Oh, if you really want to close focus with a rangefinder, get the Retina with the closeup kit and metal rails. It very precisely frames the photo and the exact focus distance
