There is the Compaq Presario v2000t line. I think it<s one of the less expensive laptop who has a Core Duo processor...

After, you have the HP dv1000t line which can be a great quality\price product.

But you must know that with a budget laptop, you will get an integrated graphics chipset, which is not very good to play games and this kind of graphics chipset steal up to 224 MB of the main RAM ( adjustable in the BIOS options ... ).

You get what the price allow you Wink

The Dell Inspiron 6400\E1505 is a very nice laptop. I<ll make a review ( if I can stop posting messages on this forum one day Wink ).
