Where to buy a used PS3?

[poncypony]

I thought that I would buy a PS3 as a Christmas present for myself I-may-have-already-preordered-the-collector's-edition-of-Kingdom-Hearts-2.5

I obviously want to get it for the best price that I can, and don't mind if it has a few scratches. I'm a bit wary of ebay.

Where should I look? What would be a good price to pay?

Game or CEX on the High Street.

Amazon if not.
