Alienware are very pricy allright. I'm wasn't the greatest fan of Dell but you can really do well from the outlet store on their website. I just picked up a fairly well spec'd machine for €1471 inc vat with three years warranty, and am very happy with it.
Its a 9400 with 17" WSXGA + screen, Gefore Go 7800 256Mb, Centrino Duo 1.86, 1 GB 667, DVD DL, 80Gb Sata, Bluetooth, WiFI, Card reader, 6 X Usb 2 ports, Firewire, Subwoofer and a nifty Windows Media Center remote control!!
Not as pretty as an Alienware but its bad looking at the same time. The GeForce needs overclocking but after that its savage enough for games. Having two processing cores is the dogs gonads for video editing though! Faster than the 2.2GHz Centrino machine I used before with Adobe Premiere.
Spec that on a Alienware and you are definatly paying a lot for looks and twaeking you can do yourself with a but of reading up. As with all outlet buys you gotta keep an eye out for the bargains.
