Yeah, 645 is a great format. I prefer my Mamiya 645AF, but the Pentax is a very capable system, although a bit chunky by comparison to the mamiya/contax equival

These were all well thought out professional camera systems, and you really can't go wrong with any of them. If you are interest in photography, and have dabbled with film (say a 35mm camera) then you really should try a 645 camera. Or, jump straight to a hasselblad and be done ;)
