I've been selling my old digital cameras as I get new ones, to help finance the upgrade... so my only digital is my Pentax *ist DL. I previously had a Minolta Z5 (12x, IS, 5mp, was never really happy due to the noise levels) and a Fuji 2800Zoom (6x, 2mp - great camera). I do still have (and sometimes use) my Pentax K1000 35mm, and I recently found what I'm pretty sure is the 35mm I was using before the K1000, which was a basic Kodak PnS.
The wife is on her second digital camera (Canon SD600) and we still have her old one, a Minolta X2 (smallest AA camera available at the time with real zoom), plus her old Canon SLR (a basic manual focus model.) Oh, and there's a 1976 Olympics special camera she picked up from a garage sale a couple years ago, too, but I don't even remember the model off the top of my head.
Somewhere in my parent's house, I think I still have my Kodak Disc camera and even my Kodak instant camera.
I'm not sure yet if I'll keep my DL around when I upgrade to a K10D, which'll hopefully happen this year sometimes... I'm leaning towards keeping it.
