Looking for laptop

Hey guys-

I'm a poor college student who is looking for a good laptop for cheap. Yeah, I know that's impossible, but here's the deal. I've only got a few hundred or so to spend, but since I don't have a lot, I'm not looking for top of the line. I'd like something at least 366mHz with a 6GB hard drive, kinda light and durable, long battery life if possible. It'd be used mainly for programming assignments, surfing internet, and such. If anyone has one they'd like to get rid of, or any thoughts on where to go, I'd appreciate it.

Thanks
