I'm selling a jtagged xbox 360 - works with latest games, and come with free style dash installed (it auto boots to the free style dash). Some people sell it to you jtagged without all the files configured.
This model has the Jasper chipset, which was the most reliable model before the slim model came out. It shows no signs of overheating (you can tell in some of the xenon board this si about to happen when the graphics start messing up). It has never red ringed, it has never been banned, and it was professionally jtagged. It works fine with kinect and has been updated so that avatars work.
It works with with retail games and xbox live games, so it would be perfect for an arcade. You can rip your game collection right onto the external hdd, message me if you'd like to talk more about how to get games on here.
This package includes
The system
Installed 250gb hdd
External 1 tb hdd (already formatted and ready to use with the jtag)
Power chord and hdmi and composite cables
Kinect
message me with an offer, I'm not exactly sure what to charge, just don't insult me with a low ball offer

I will only ship to the USA, well.. unless you're willing to send me a money order or check and wait for it to clear.
