I managed to win an auction for a large-format camera on eBay. It's a Graflex Crown Special (a press camera, mostly) with a Schneider Xenar f4.5/135mm lens and Syncro Compur Shutter. Also a bunch of other things like a case and a tripod, and two film pack holders and thirteen sheet film holders. A good complete setup for getting going in large-format, definitely. I may look around for a Polaroid back, but I don't think that's going to be critical for the stuff I want to do.
Some photos:
