To give another data point on the absolute bargain, bordering on stealing end, I bought a kit a few months ago on Photrio. Included a non-mirror lock-up body with metered prism, 55mm f/3.5, 200mm f/4 (both with lens cases), and accessory grip for $400 USD. Just so happened to be a local seller, so I also saved on shipping and fees.

Thank you, everyone, for the advice. I really like 6x7 format and I do wet print in my darkroom. I know I haven't been offered a bargain, but I just wanted to be sure that I don't overpay by a huge margin. The friend lent me the camera and I already shot a few rolls. I'm getting well with it. I have about one month to make up my mind about it. If I'm not buying this one, maybe I shall look on ebay and bring one from Japan (which means import taxes).
