Well I have to chime in here... nobody mentioned another jewel - the Koni Rapid Omega. A real workhorse of a camera, 6x7 (OK, if you only have a 6x6 enlarger, shoot square in your head) and built like a tank. Limited to only 4 lenses (one of which you probably will never find) but great optics. You can pick them up very reasonable on epay. Lately there have been several in the $100 to $150 range, and you can have Greg Weber do a CLA or repair if needed.
