thanks in advance.

 

i would suggest the Sony VAIO VGN-FZ160E/B 15.4" Notebook PC (Intel Core 2 Duo Processor T7300, 2 GB RAM, 200 GB Hard Drive, Vista Premium) it is $1399 on sale at amazon. but if you want a warranty, i'd suggest buying from sonystyle.com


but w/ your two preferences, the reason the 630 is more expensive is because it has the better graphics card. and faster hard drive.

 

I would suggest the Dell D630 as well or if you can do with a WS Display the D830. The D830 is the best bang for the buck. I configured it with a T7300, XP Pro, 120GB HDD, 1 GB mem for under a $1000 and it comes with a 3 yr warranty.
