Unless there is a feature you really want, just get one with at least an f2.0 lens, great working condition, and a battery solution that works for you. Many of them used mercury batteries that are no longer available. There are way's around it with hearing aid batteries or modifications to the camera, but you should be aware of it. Something else to consider is an Olympus OM1 (fully manual, mercury battery) or OM2 (aperture priority+manual, available battery). It is as compact as the bigger yashica's and about as compact as an SLR can be.
If you are considering an XA-series camera, it is really, really small, really, really quiet. The downside is that it is really hard to focus and handle. That is the trade off for the pocketability. I've had a few of them over the years as my carry-in-my-bag-all-the-time camera. It is a very unique camera, but I don't think it is a great camera to shoot with regularly.
