I put a Canon F1 on top of my car, got in and drove off. I noticed something small and balck going down the asphalt road in my rear view mirror. I turned around and went back and picked it up. The light meter stopped working, but everything else on the camera worked fine. I had it for over 3 more years until someone in Philadelphia stole it from me.
Buy a Canon F1 (the old one) - when it breaks, it will still work.
