i dont know what kind of uses you plan of having your notebook for but...
i like my computer to be able to handle whatever i throw at it..i also play a few games that require it. i just ordered a pretty much completely top-of-the-like notebook from ibuypower.com and it came to $1600 shipped
i know you said 1000, but for what you're asking, you could probably piece together something for that price.. stats on the one i ordered are
-Amd athlon 64 3700+
-1024 corsair ddr400 ram
-60gig hd at 7200rpm
-Mobility 128mb radeon 9700 pro 256-bit 3dvideo
-8x dual format dvd-r/rw 16x cd-r/rw
-built in wireless, mouse, painted blue.
basically i maxxed out all the options on their site (the laptop is named batallion turbo 2)
it also comes with a carrying case and half-life 2, i think its value cant be beat, that is, if you play games or stress your computer a lot. check out some models on their site, i like it because its much more personal, theyre all built just for you. also try zeuspc.com
