I got a launch 360, which had no problems as far as I can remember. Then I got a 360 Elite that red ringed once years ago. I got it repaired, but down the line I got that "E74" disc reading error. Microsoft wouldn't fix mine, so, I had to lightly pound on it to get it to read discs (which worked most of the time). Eventually that stopped working. A more or less a month or so after that I got my current 360, which is the Star Wars special edition slim, which is pretty rad.
