With cameras being relatively inexpensive, I would buy several of them and then decide which to keep.
I'm partial to Nikon, Pentax, Minolta, Rolleiflex and Olympus (in that order). I also tried a buddy's Canon AE-1 and liked that quite a bit, and I always thought the Canon F-1 looked awesome.
Finding which is best for you is a very personal matter, because what feels nice in my hands might not feel so good for you. Or it might be perfect for you.
