Ok so I found someone selling an xbox that works great but is banned on xbl, does anyone know if I can do something to unban it, or should I just not buy it, its selling for $30.

I wouldnt, when your banned its a console ban and you either have to use some hardcore hacks to unban or replace the motherboard because its console banned.
