At first I was contemplating reviewing each guide separately, however, in the end I could not separate the two.
The Xbox 360 Red Light Fix guide is written by James Dean and the 3 Red Light Fix guide is written by Chris Jones. Both are very good at explaining how to repair your Xbox and get you back up and running in the same day.
Both guides are easy step by step guides that can be followed by anyone. Both guides claim to be able to have you back playing your Xbox within an hour with the 3 Red Light Fix guide going in further and claiming to have you back playing within 37 minutes. Overall both guides will easily have you back playing your Xbox in under 1 hour.
When purchasing any repair guide online I have always considered that a money back guarantee is essential. Both repair guides offer a money back guarantee, with the Xbox 360 Red Light Fix Repair Guide offering a 60 day guarantee with Xbox 360 Red Light Fix offering 56 days.
Both guides also allow you to fix other errors such as freeze ups, distorted graphics and the E74 error.
Both guides are among the most popular are both highly rated by gamers.
My rating of the two guides can be found at Xbox 360 Red Light Fix Review and Xbox 360 Red Light Fix
It should be remembered that if you decide to open your console you will void your warranty .If you are concerned about this then I suggest you contact Microsoft before purchasing either guide.
