Trading Xbox 360 for PS3 - best places for best prices??

[broken biscuit]

I have decided to trade my Xbox 360 Elite in for a PS3. Only have a few games - Forza 3, COD MW2 and Black Ops, NFS Pro Street and Blazing Angels. I know ASDA is better than Game for trade in prices on games, but what about consoles? I don't mind trading against a pre-owned PS3 - but which do I go for - a PS3 slim or original, and with which memory??

Too many Ps3 choices. I want Need For Speed, COD Black Ops and GT5 as my 3 main games to aim for. Any recommendations please?

With the new Xbox model out now, you'll likely get very little for your elite as a trade in. You'll likely get a better deal privately selling, and then perhaps trade in the games.
