Yashica FX-3, FX-2 ... as Garageboy suggested, the FX-D is good, too, I've heard.

How do you define bargain?

The FX-3 can be had for $50 and it's a durable machine that requires littler or no maintenance; it sports a basic but consistently-good meter; it also accepts a range of great lenses. These things make it a bargain in my book.
