I just went for the 120Gb version. I stopped trying to work out which was the better deal as everyday there was a better option and I would have never bought it, so I finally went to Argos and got the 120Gb, 3 games and extra controller for just short of £280
Games list so far:-
Little Big World
Unchartered 2
Grid
Pure
Quantum of Solace
Lost
COD-MW2
P.S. anyone know who 'PureTuG' is? He's just invited as a friend!
