It isn't medium format though. And, to be truly ultimately cool, the Deardorff must be mounted on a wood tripod and be fitted with a Dagor (preferably German version) lens.
They're a pretty good chick magnet, too - they don't attract the nutty ones like a Harley does.
The 3x4 Graphics and the Mamiya are MF and pretty cool. Any TLR or Graphic is cool just by being a TLR or Graphic.
