Modded Xbox 360 with 31 games and 20GB hard drive

I am selling a modded Xbox 360 that comes with 31 burned games. The console is a essentially a premium system because it is a core but I have upgraded it with a 20GB hard drive and component HD cables. It works like new and has the SAMSUNG drive (the best drive for modding).

The games are:

1. Command & Conquer 3

2. NBA Street Homecourt

3. Splinter Cell Double Agent

4. Project Gotham Racing 3

5. Gears of War

6. Battle Station Midway

7. Battlefield 2: Modern Combat

8. Marvel: Ultimate Alliance

9. Blazing Angels

10. TMNT

11. Chromehounds

12. Dead Rising

13. Tiger Woods 2007

14. Ghost Recon Advanced Warfighter

15. Lego Star Wars 2

16. Lost Planet

17. Rainbow Six: Las Vegas

18. Need for Speed Carbon

19. Dead or Alive 4

20. WWE Smackdown Vs. Raw

21. Saints Row

22. Madden 2007

23. Call of Duty 3

24. Viva Pinata

25. Kameo: Elements of Power

26. Tomb Raider: Legend

27. Tony Hawk's Project 8

28. Spider-Man 3

29. King Kong

30. Crackdown

31. Def Jam Icon

Price is $550 or best offer.

I will consider all reasonable trades, and I am particularly interested in trading for a tablet pc laptop.
