1. HP Pavilion dv6000t
2. Dell Inspiron E1505 ( I have this model. Very nice computer ).
3. Asus ( they are not well-known in America, but you must take a look to Asus. The quality of their product is remarquable )
4. Toshiba

For a good graphics solution, take an ATi Mobility Radeon X1400 or above ( GeForce Go 7400 on the nVIDIA side ).
