I was kicking around my local camera shop the other day, when I found a bunch of Mamiyas. Two RB67s: back, dark slide, WLVF and lens, both $100. There were also some 645s, old and new w/lenses for around $150. I didn't test them, but they seemed to be okay (shop said they were alright but as-is.) Tempting, very tempting Even though I'd likely almost never use them ... $100 isn't that much money is it?
