My first XB360 got the RROD. I went out and bought an Elite on the same day, sent the original back to MS who fixed it and sent it back within a week. I then sold it to a guy at work for £100.
My Elite then got the RROD, or certainly symptoms of it. I ordered an Elite Jasper from Ebay minus the hard drive. It arrived the next day, I swapped HD's over and it's been perfect for months now. Still have my Elite in a box in the loft. May send it off to MS to fix and then sell when I get it back.
Elite Jasper is mint though. Quiet too.
