I had a large Canon FD body collection. Last year it struck me that I was only using the T90s, so purged most of the rest. I can't, however, bring myself to part with the F1 or New F1.
I have two drawers full of Minolta gear I no longer use, but can't part with. The XD-11 is such a sweet camera.
Aaaaaand I have a pile of EOS gear, multiple copies of several bodies. Hey, you never know when one will break down...
I figure as long as I'm not tripping over the stuff, it can stay.
