i wanna buy a new gaming system but i dunno which one to buy...... i've got a playstation (not hooked up though), an xbox (great system) and a psp (great portable system)

Ninetendo wii

has pretty bad games on it and crap graphics but has a good price range and multiplayer.

Playstation 2

good games, good graphics, good price range. but a bit old

Playstation 3

has great games and great graphics but out of my price range ($1000 AU!!!! not payin that much for a system)

Xbox 360

has great games like halo 3 and excellent graphics and in my price range but "apparently" has lots of errors and freezes up alot.

any help would be great
