go to a used game store or site- Hastings(gohastings.com) game exchange or game stop- all of them sell used game systems and they are tested before they are bought back and sold to you. And if you have any problems with the system- most of the time they will exchange it for you or give you a refund (usually for in store credit).
Hastings had them on sale for $70 on black friday. I don't remember what they are originally.
Less hassle this way!
