When I was looking for a nice, small, portable point and shoot, I settled on the Pentax Optio series. I looked at the casios, but what I found was that the response time was too slow. The Pentax's are based on the casio internals, but have a slightly larger body, and much better response times. They're definitely worth a look.
BTW, this would be better placed in Off Topic, since this has nothing to do with Imprezas.
