only one RROD with a Core that I immediately returned to Best Buy for a refund
my launch 360 is still going strong but I gave it away to someone else long ago
my current Falcon works real well, I got it for HDMI and the increased reliability, it's modded and the discs spin at 8x, making the unit pretty tolerable as far as DVD-ROM whining goes, without affecting the load times whatsoever... even if those high-pitched fans are still a bit over the top I can now play a quiet game without being distracted by an hair dryer whining in the background
