EEE PC 900 ha extended battery

[Spekkio]

i'm trying to find where i can get an extended battery for the 900 ha (different shape from 900's i believe so i need a particular model) so i can try to eek closer to a full day's worth of use out of it. unfortunately, the battery that ships with it is a piddling little 4 cell dealie, though it's capable of 4-5 hrs worth of operation alone. unfortunately i'm having a rough time finding anyone that looks vaguely reputable that sells additional batteries for the device (i've been to asus's website, newegg, tiger direct, etc.) does anyone have a favorite battery retailer that would sell a branded or aftermarket battery for the device that could keep it juiced up for longer?

There are some 10400mAh batteries compatible with the 900HA. Not sure how reputable those sellers are, but it's a place to start I guess.
