TBH really any 35mm slr with a fast-ish 50 will be a kick as intro to film. Buy something local and cheap (Craigslist/kijiji are good, just do a thorough inspection) or hit up your local camera shop to see if they have a used section. http://keh.com also has a really large selection of 35mm gear.
i just recently got my first 35mm setup. pentax spotmatic f ($30), helios 44-M ($45) and a supertak 28mm f/3.5 ($60) all on ebay including shipping. I'm having so much fun with it that i'm going to get all of the supplies to develop myself, which looks like itll run about $70.
