Actually Mike I think ebay is great. I've just had problems with Japanese sellers and you can perform the same search for a Mamiya 6 to see what I mean. I'm batting about .500 with them - recently had to return a Perfect Condition/Like New Pentax 28 3.5 because it had damage to the rear lens element.
I did get a beautiful Fuji TX-2 but that was a couple of years ago, and that was tempered by having to return 2 Fuji GW690s as they definitely were not as described, or what was shown. Ended up buying that locally.
I've bought awesome stuff off ebay and still highly recommend it. But it seems when I base my purchases from the US or EU I have much much better luck.
