even with a "bargain basement price, i'd still pass on it. if you want a 6x6 camera, get a hasselblad 503cw or a 553/555 elx/eld. you can get a motor winder for the 503 as well, even the most current v-series zeiss glass, which is just as good as the glass they are putting in the current line-up of cameras from sinar/leaf. a photographer i assist for has the hy6 with the whole set of lenses for it with a sinar D/B. he's selling it to revert back to hasselblad v-series with the newer phase p65+.
albeit, the sound of the mirror box in th hy6/AFi is to die for! ka-(insert hocking up a loogie noise here

) and the grip is like soft butter in your hand. i've never held a camera that is so comfortable, and i probably never will again!
but if i were you, i'd think long and hard about this one. there are millions of v-series cameras out there, and millions of lenses for it. not autofocus, but much cheaper in the long run. and just as good of quality (i'm referring to the cfi,cfe series lenses here)
just my 2 cents
