We have Dell Inspirons from the 2000 series all the way up to the 6000 series, we also have a few Latitude D810's and they all work pretty good, even though they are used as dekstops and run 24 X 7. Every once in a while Dell will run a 30% off laptop coupon allowing you to get one at a steal. Checkout www.hot-deals.org or signup to Dell's mailing list.
