I wish I could help you out because it looks like really nice gear, but a) I'v already got a 645, b) I'm on a budget, and c) there's no waist-level finder listed and that's what I'm interested in. That 80mm f1.9 might be interesting but I wouldn't need any of the other stuff.
I'm interested in picking up a medium format set up, but I know nothing about then ad of yet. I wouldn't know what to offer you, so I'm waiting till I see some prices before I see what I can afford.
