I have several FSU cameras: a FED2, Salut-S, Kiev 6C, and Pentacon Six.
My LF cameras are not FSU. In 4x5, I have several Speed Graphics and an Orbit monorail. The old press cameras go cheap, especially if they are plain (Pre-Anniversary). The monorail cameras are cheap as they are a pain to lug around. Both will produce marvelous photos.
