You guys never make anything easy..
I'm quitting this rambling, leaving all the possibilites open, waiting what camera will "fall into my lap".. Will it be a small-ish fuji 645? Or a square bronica? Maybe an RB again - perhaps with a 6x8 back this time? I wonder..
If I saw one for nice price I'd jump on it without hesitation - as far as I have read it ought to be the perfect compromise between the size of the negative and the size of the camera
