If you got the budget, then I recommend the Lenovo ThinkPad W510 series which starts at $1,300 and simply shoots up from there. Note that is the current discounted sale price.http://shop.lenovo.com/SEUILibrary/controller/e/web/LenovoPortal/en_US/catalog.workflow:category.details?current-catalog-id=12F0696583E04D86B9B79B0FEC01C087¤t-category-id=FB35C8C3EB6B4076848E1488F7083D90&action=init
I have person experience with ThinkPads. I bought my IBM ThinkPad back in 2002 and I am still using it. It's rock solid. Of course it cost me an arm and a leg at $2,200+.
