I bought doubles, even triples, of favorite 35mm SLRS 10+ years ago when many in nice shape went for very little money. Mint or EXC+ medium format gear(Bronica and Mamiya) wasn't much more. If doing it again today, I'd probably skip it, due mostly to the thinned ranks of qualified repair talent. Sure, there are the Sherry Krauters and Sover Wongs of this world, but 25-40 year-old prosumer/amateur 35mm SLRs are tough to get fixed and easier just to pitch. When pros turned away from film, medium format repairs got scarce, too. I'm a light film user and trust my back-ups will last me. I stopped buying film gear around 5 years ago mainly because the quality had slipped dramatically.
