Is a Xbox 360 that has been previously repaired from some sort of error or red ring more likely to fail again than having a new Xbox fail? And are the repaired ones just as good as when you first bought it?
It depends on who repaired it. If it was MS it will probably last for a long while. I have a refurb from MS thats been running for a good 3 years now. If it was repaired by someone else other than MS, it depends on how good of a job they do. It may last anywhere from a week to forever.
