I just picked up an Acer Aspire 3003CLi for $616 shipped (no tax) at Newegg. It has terrible battery life because of the 4 cell battery (<1.5 hours), but can be upgraded to a better 8 cell battery for under $100 on Ebay. Throw in some more RAM (it only comes with 256MB) and you've got a decent AMD Mobile Sempr0n based laptop for cheap. Of course you could pick up a Dell Inspiron 6000 for $799 and add on more memory, but chances are you'll have to pay shipping and handling and tax which will bump it up at least another $100.
