Suspect, a tip from me: Buy a Gamecube! You won't regret it. For 120 dollars you've got one, including the magnificent Resident Evil 4. And it's 3 times smaller than the xbox (really, not kidding).
Everyone thinks PS2 is the best, also because it sells so good, but that's because everyone who own's one, has to buy a second and maybe a third when they break.
