I've just picked up a C330 for my first foray into MF and I've got to say I am super impressed with it. On my list of camera's I researched and would like to own are the Mamiya RB/RZ67, Pentax 67 II, Mamiya 645 and of course a Hassy of some kind.
But the build quality and everything about the C330 far exceeded anything I was prepared for coming from 35mm.
