I have a Canon 5D and I nevvvvver use it.
thats a lovely camera - although sold mine as I never use it either.
keep an eye out for the pentax k1000/kx/km or the pentax mx. both go for significantly less that the nikon or olympus equivalent, and lens are good and cheap also. pentax made pro gear in the 70s/early 80s, so the stuff is as good as the equiavlent. also pentax never changed their lens mount(unlike canon and nikon), so you can use any pentax lens from 1975 on any camera produced subsequently.
