You'd actually have quite a bit of options if you don't mind ugly looking camera and have $250 to spend. Very user Mamiya 645 and Bronica are quite available and in your price range. You may even be able to buy old RBs. If you buy from places like KEH, you can get a fully functional camera with a warranty. Unless you like TLR and that particular camera, I don't see a need to jump-in. By the way, Rolleicord and other TLRs are in that price range too....
