Mine is pretty old, never had any issues...
It predates the hdmi port consoles, black paint etc. Its a 20 gb.
When I purchased it was at release, for $399.99 I believe, and were only 2 versions.
Think it was called the "xbox 360 Premium" back then.
Where the distinguishing factors were that it came with a wireless controller, chrome plate on disc tray, & a 20 gb hard drive etc.
Still running like a champ.
Some of us have seem to have bad luck.
I have heard of people going through 5 + consoles.
Always thought it has to be user error in there somewhere. But everyone I encountered has assured me that it isn't.
Guess its very bad luck.
