Good film cameras are a dime a dozen these days. Any of the major brands will do just fine. Buy from a dealer and get a warantee. Look for a deal including two or three lenses.
Ebay is ok if you follow all the usual precautions on ebay. Many camera shops have ebay stores and will take the camera back if there are any problems but you won't save that much. A local dealer is better.
Don't give them the asking price. Take 20% off their asking and if they say no turn and head for the door. They'll probably call you back before your hand hits the door.
Also a camera repair shop can be a good place to pick up a camera. People abandon them because they don't want to pay the repair costs. If you stick with the top three or four brands you will have a better choice of lenses and accessories.
Repair shop is a good idea...I didn't think of that.
