I have a HALO 3 one, boxed, used, broken.
And a MW2 one, boxed, new, unused. Nabbed the game from it and gave it away, I bought the prestige too. Hated the game.
Then I have my Elite (Family console)
Arcade with 250GB hard drive (My one)
And finally our old dead premium.
I might invest in the R2-D2 console, almost out of space on my 250GB.
