Why does the OP want XP anyway? As far as i can tell, soon nobody will be using it on new laptops or desktops, or indeed netbooks, with the release of Windows 7.
What you smoking lol I got a vista laptop and got Xp also on it (duel booted) And i never use vista side some days i think about geting rid of it but what the heck why toss a legit vista copy out lol it only useing 20 gbs of my hard drive
On topic
Its going to be hard to find one like you want but the members before me look like they got you hooked up but just as a option, Buy vista wipe the drive install xp Might be cheaper.
EDIT : Off topic again i am planing on building a computer in the next 2 years and plan on useing windows xp SP2
