Hi,
A kid in my school is selling a Xbox 360 with the 20 GB HD and 1 wireless controller, and cables. He said he will sell it under $200.00.
I am wondering if this is a Good Deal or would should I buy it from Gamestop?
Also this would be my 1st 360, what should I look out for (errors,problems,etc) I already know about RROD anything else.

Thanks Alot,
