Best place to buy a pre-owned X-box 360?

[Goochie]

The wife has at last said yes to me buying my "colleagues" x-box 360 "for just £20"

So, now I need to find a shop to buy one and the likely candidates seem to be Game and Blockbuster.

But what do I need to look for and how much should I be paying?

I was hoping to get something for less than £100

eBay is probably the place to start.

I bought one for £65 from play.com. If you have to search through the 3rd party listings but there is some good stuff in there. Mine was without cables or a HD though, I'm guessing you'll need those bits...
