Seems like a pretty good deal if you're not too worried about getting the new version when it comes out in a couple of weeks.
Base price is £149.99 for Elite, Wireless Entertainment Pack (includes additional black controller, Pure and Lego Batman) and HDMI cable.
For an extra £20 can get one of...
Red Dead Redemption, Alan Wake, Fifa 10, Tiger Woods PGA Tour 11, Battlefield Bad Company 2, Fifa World Cup 2010 or Skate 3
Considering I haven't seen Red Dead for less than £35 anywhere that would be my choice!
