Ok, so my brother is going to college and we are sticking him with our current digital camera, a 3.2MP fujiflim. It's great, except for the fact the it is slow, and since my father's job includes going to airshows we need some speed. I'm looking at around $400 but that's flexible. I want to know what should I look for in a camera and what models out there look good right now. Thanks.
