Deadman, I got a couple recommendations for you.
The IBM thinkpad is a business grade laptop that's built very rugged. Here's a link to amazon who currently has a nicely loaded one on sale and well within you budget.

Or I also really like the HP dv9000 series. It's very fully loaded, lots of RAM and had a very nice quality screen and is also on sale. I like the HP better because you get more bang for the buck.
