I'm glad the C220 is larger than the Rolleicord/Autocord and that I'm so picky about size.
A friend offered me a lens that needed some shutter work. I was thinking about taking it but then I'd want a body to use it with... and that lens was a telephoto so I would have wanted a wider lens to go with it... and suddenly I would have found myself with a fourth TLR. I'm still testing the YashicaMat I was given to repair recently before passing that on to a friend.
I've used a Bronica SQ-A, several TLRs and a few folders as I went on a medium format purchasing exploration myself. I like walkabout cameras so the TLRs and folders fit me better than the SQ-A, despite the obvious value in interchangeable lenses. The Autocord, Rolleicord and Zenobia are my favorites so far. I still use the SQ-A when I'm doing slightly more studio style shooting (and I would probably use it much more if I had a 50mm lens for it) but be careful about thinking 'flexible == preferable'. A MF camera you can put in your pocket like the Zenobia serves a different roll than a system camera.
