G or no G does not really matter. You can, if you are patient, get a focal plane shutter Bronica like an S2 or S2A for 200. Pentacon Six is now within your budget, but I wouldnt recommend buying without trying. Pentacon Sixes are prone to have a failure in the film advance mechanism. Rolleichords are within your budget now too as well as a bunch of other TLRs like the Yashica mentioned above.
