The new Falcon Motherboard 360s are out now arent they? that should pretty much take care of the RROD in most cases as long as you take care of it and dont get a piggy back cooler (like teh Nyko one) and dont put it in ur oven while playing it. etc.
mine actually did get teh RROD so i took it back to the store, they plugged it in, didnt show up again, said "we cant take this, not trying to be a dick but their basically looking for a reason to fire us emplyees lately" so i was understanding, took it home, has been fine since. (weird i know, it was the 3 lights, not 4, too. explain that one lol)
