I still shoot quite a bit with film gear and I've actually accumulated a fairly large collection of film cameras and manual focus lenses in recent years. Most of what drives me is the prices that I can pick this stuff up for. It's just really hard to resist. I try to be fair with my fim cameras and rotate through them, but still I think I need to take a breather. I've got about seven cameras currently loaded with film in various degrees of completion and I'm getting a little bogged down.
These days, I buy most of my used gear from eBay. KEH has been a good source, as has Robert's Camera, of Indianapolis. Another good source, if you're willing to take the chance with as-is stuff, is Goodwill's auction site. I've picked up quite a few pieces there. Locally, this overgrwon cowtown I live in was down to two real camera shops left until several months ago, when one of them closed. I miss that place. I found some good used deals at that place. The last survivng camera store in Houston carries some used gear, but they've priced it at book value, so I don't really have much interest in it. I've run across some good deals at that place in the past, but not so much anymore. Just as well, I suppose.
