My mom just got
this camera. It's $519 though, and I know that's technically out of your range, but if size isn't a huge factor for you, I love this one. Plus, it has some pretty nifty features like how it can take 5 pics in 1 sec just by holding down the button. And, if you turn the resolution down to 1, 2 or 3 MP you can capture 40 frames in a second. I don't know how much use this will be to you, but it was awesome to take paintball action-shots with.
