I shoot with various MF systems such as Mamiya 645, RB67 and Bronica and I always try to find a reason to sell my P6 stuff but I just can't let it go. Even with all the quirks and reliability issues it's one gorgeous camera and lenses are bang for the buck. most of the lenses have nice coverage area so I mostly use it for handheld tilt/shift stuff [ http://www.flickr.com/photos/overdear/tags/ts/ ] lately. If the price is nice then it's not much of a risk because you can always sell your stuff later. one extra plus is that most of the lenses available are quite fast, in MF terms.
