XA would be my first choice. Nice camera, I sent my Mom to Thailand with one in 1981 and she had a blast. Second choice would be a Cannon Sureshot. Usually 10 bucks, auto everything, if you lose it, oh well. I bought a couple for aerial kite photography, use one as my everyday keep in the car camera.
Third choice... Kodak Retina IIa. You need a meter but it's bullet proof, takes great photos no matter what lens is on it, and can be gotten for under 30 bucks. And I don't think anyone would steal it. The Schneider or Kodak lens models are wonderful but any of them will give you great images.
