I love my Canonet dearly. My all time favorite image was taken with it.

That said, 100 pounds for a canonet is just silly. I think I paid $45, with the aged case. For that price, you could get an OM1 with 50mm lens. I was shocked to see that the OM1 was nearly the same size/weight as the Canonet. Heck, a Nikon FE with a 50mm 2.0 lens isn't too much bigger. Unless you want the really quiet shutter of the Canonet (and, sometimes, I do), the OM1 is a better bet.
