I'm down to 3 6x6 cameras (well, I've got two S2a bodies, so count 4 if you must)

Bronica S2a system--versatile, modular system that does just about anything I need from a MF camera.

Voigtlander Superb TLR--beautiful, innovative, lightweight piece of history, that's quiet and inconspicuous for street shooting.

Voigtlander Perkeo II folder--the "pocketblad" that goes anywhere, smaller than many 35mm rangefinder cameras.
