What made you go to a medium format vs. sticking with a 35mm format? I was originally looking at getting an F100 but some Hasselblads came up on Kijiji as well and it crossed my mind. But then they seem quite a bit more expensive and I'd have to get more lenses so I'm not sure why one would make the jump unless they were enlarging photos by a considerable margin.
PS I didn't find an F100 anyways
