This is for a friend of mine. He has a mid-2009 13" MBP (not sure of exact specs other than it's the midrange) that is in need of a top case. Taking it to the Apple Store is likely much too expensive, and the machine has some pretty extensive cosmetic damage from a drop (and probably internal as well, but I'm not sure exactly what). Where can you buy a top case that will be trustworthy and not break the bank? Is it even worth it? Thanks!
