I think you're a good candidate for a press camera. If you can develope your own B/W now, then all you need is a drum and roller to develope sheet film. Just think, instead of having to wait to finish a roll of film so that it can be developed, you can take that one shot, develope it, and get right down to the business of printing. Of course you can always get a roll film adapter if you're so inclined. Something to consider.
