I just requested a coffin for my third.. I bought an elite with the man. date of 4/2/08, and it keeps locking up with white and gray vertical lines (regardless of game). No RRoD though.. I'm guessing the GPU is shitting out. I'm sure a RRoD is just around the corner though, although it's a Falcon. So, it's still under the 1 year warranty, and hopefully they'll fix it.
I had bought an Elite after receiving back my last console hoping to escape the merry go round of refurbs, and it sucks to see this happening STILL. I have this bad feeling that they'll see it work for 30 seconds, and just ship it back to me without repairing it.
