There's always a buyers market for these things but you have to find the right kind of place.
This.
People still shoot to film these days.
....Not me but lots of photographers of all ages shoot film and many even prefer film - It's not just a generational thing. Some shoot both film and DSLR.
The glass quality of the SLR Canon lenses will not have changed and so Hedge's idea of buying a Canon DSLR digital body is a good one depending what sort of photography you want to do. Autofocus is primarily what you won't gain.
If you are after a smaller size DSLR, Canon offer the 100D which is a similar size to a 'bridge' camera. My daughter has one which I have used (I use a 70D with long L lenses) and it's very good indeed in my opinion.
If you have a limited budget and you are happy to join and be active on a good forum such as TalkPhotography you can buy very good condition previously loved gear when you eventually qualify for their Classifieds. Up to you of course, but eBay for camera bodies/lenses is always going to have a higher risk factor in my opinion.
