@QueenOfNowhere oldest digital cameras take pictures that are terrible, trust me, and they look nothing like film cameras.
If you want a good quality old film camera, go with a Kodak 35 Rangefinder. They are sexy, hefty, and you can find them for decent prices on ebay.
If you are feeling adventurous, go for the Holga. These things are super fun and unpredictable, and they take 120 film, which isn’t too cheap, but the images are worth every penny.
@Lightlyseared Wal Mart still stocks 35mm film, and there are several dozen online retailers that stock film. Film is NOT dead.
