A while back I sold my RZ system, I found it was just to much weight for tromping through the mountains with, then after selling it I realized I didn't have any medium formats left. I would be interested in something like a Mamiya 645, Bronica or something along those lines, no TLRs. If I can find one of comparable value to the drum. I have seen the drum for 350, and this one appears to be new, I sold the processor with all the other drums, but had forgotten this one still in its box with instructions and the receipt of purchase.
