Thanks! I didn't pick it up yet, but will today. A semi-local camera shop took one, new in box, in on trade along with a bunch of other RB and RZ gear, but for $150 NIB, I'm going for it.
Unfortunately everything that was taken in on trade except for the prism, a few Mamiya No.1 and No.2 hoods, and 2 120 backs were scooped up by a guy from Rochester. From what I was told the RB stuff was used and abused, but the RZ gear was like new.
