Hello All! I'm thinking of purchasing a used 2012 MacBook Pro model md104/lla. The problem is that I'm fairly picky and would really like to get a mint to near mint fully functional laptop. I know this is asking a lot based on the age. If I can't find one reasonably I may purchase a newer retina model. I already have many accessories for this model year for my wife's laptop. Does anyone know of a good/reliable source for this model?
