I guess I'm too late, but how about a Graflex? Get a multi-coated Ektar on one (look for the little 'L" in a circle) and you have world class sharpness, plus 24 shutter speeds to fine tune your exposure. Get the 12 exposure (22 or rh-12, Graflex not Graflock) back and you don't need the RB feature (revolving back). Plus you can use sheet film backs as well. They can be found for under 200usd with back if you're just a little bit lucky.
