I have & use a 2000fc/m, which works fine. No issues, it's been reliable. I also have a fc/w and and old fc body as backup/parts, just because I like fiddling with them.
As people mentioned, the foil shutters of the 1600/1000f & 2000's are prone to damage if you poke them when the back is off - its not that different from 35mm SLR shutters, but there you are less likely to drop something heavy (like a film back) on it. Pros working fast were more prone to pushing the corner of a film back into the shutter, and in a shoot, you can change that back a lot! However the foil shutters are what allowed the 1/2000 speed in that small body.
The current part that is not replaceable in the body is the magnetic release and coil, which are no longer available. Shutter curtain are still available (not from Hasselblad) but the cost of putting one is exceeds a used replacement (unless you do it yourself, then it's about the same price...).
The 2000's are quite loud and sharp when the shutter is released. In "C" mode, it works like a 500C. In "F" mode (set on both lens and body) it works with the focal plane shutter. Older "C" only lenses "can" be uesd in "F" mode by setting the C-shutter to "B". However, Hasselblad warns you that the timing may be off if the lens has not been recently serviced - basically if the lens is too slow opening into B, the FP shutter may trigger too early.
Just for the record, I also use a 203fe (my favourite) and an really old but working 1000f (which is surprisingly nice), my 500cx gets the least amount of use.
