any netbook with the nvidia ion chipset is probably the best choice for the price
the ion is equipped with the 9400M i believe. ex: Lenovo S12 (only cost about$700)

BUT if ion is really too weak for your liking (plus money don't matter for you..)
then just get the ASUS N80p, video card is better than the 9600m gt and it's 14inchs
