I have always reccomened sagers to everyone, cuse they are cheep, quality, kickass computers. and check out the following www.talknotebooks.com
I have done a lot of research into buying gaming laptops myself and found the ones I like the best to be Hp Pavilion zd8000 and Gamer Explorer x7 7000 I found the HP notebook to be the cheapest notebook for what I wanted in gaming requirements. And The Explorer x7 to be the second cheapest, but also had the addition of 5.1 speakers, which I find cool.
heres a post i made for someone else It included a second 12 cell battrie a carrying case and its a pentium m so the battery should last a little longer then the p4 sager.
