Assuming the OP wants a digital Hasselblad V and not lens adapters to fit other systems, the recent 50 megapixel Hasselblad 907x package is probably what I'd go with. A survey of alternative offerings on *Bay didn't look so hot: There's Phase One and the original Hassy CFV, but these are old enough to require Compact Flash media and Firewire hookups. Which might be fine if they were selling for a few hundred bucks, but for the asking prices that I'm seeing, I wouldn't touch 'em. At the moment 4500 USD seems to be on the low end of *Bay prices for the 907x package which includes the X-system body.
BTW, what's the deal with Hasselblad X2D Mk 1 BTW? Seems relatively "cheap" at ~4000 USD for 100 megapixels. If it's only a matter of so-so autofocus, that might be tolerable.
