Yes get a 360,The best pack to get is,I forget what it's called but it's around $370.
It comes with 2 games,headset,1 month gold membership free ftw,Wireless controller,Extra cords and some other shit.
I have a 360,Just got like 1-2weeks ago.
I love Forza Motor Sport.
I would suggest not getting Halo 3 but call of duty 4,or Forza Motorsport 2,They both own.
