Hey just wanted to give anyone thinking of buying a 360 used a little heads up.
Recently Microsoft did a sweep and is banning any and all hacked boxes, I have flashed about 12 xbox 360s for friends and all have been banned. Xbox IS NOT BANNING USER ACCOUNTS, THEY ARE BANNING THE BOXES THEMSELVES FROM LIVE.
This being said lots of people are starting to flood the market with used xbox 360s, I STRONGLY recommend making sure you can still log into xbox live before purchasing the 360.
Also do not purchase an open item Xbox 360, banned people have been purchasing New Xbox 360s and swapping out internals and returning the items, so basically its a banned 360 in a new shell.
Just a little heads up, I've already caught a guy trying to pawn one of these banned 360s off on someone else on another forum that I'm a moderator on.
If your fine with not being able to get on xbox live then there is nothing wrong with buying one of these 360s, I now use my modded one as a media center extender, and have purchased a new one to play games online.
