a couple points i haven't seen mentioned yet.
The Medalist II has a viewfinder that compensates for parallax -- it also is pretty good sized, considering how it looks on the outside. It's a good view, with the rangefinder window very close and directly below the view.
One thing to consider with folders is how sturdy the front standard is. Zeiss cameras are very good for this ... the Super Ikonta C is rock solid. A sloppy front standard will make things look fuzzy quick.
