Phase One 645AF (Mamiya 645AFD III) - Good or Bad?

[haring]

Is there anybody who uses Phase One 645AF (Mamiya 645AFD III?)
Is the AF fast (relatively) and accurate?
Which digital back do you recommend?

Thanks!

AF is gonna be reliable but not exactly fast. Ive never actually used one, but from all other experience with MF, autofocus is like molasses uphill.

Depending on what youre doing you may be better off with manual focus anyways.

Too rich for my blood but it would be nice to hold the value of a car in my hands
I think you can rent one from Calumet Photographic. I think they lease them too which may be the ticket...
