Hey guys, I'm sure we've all heard of how crappy these macbook pro chargers are with their fraying and so forth. Now the middle of my apple charger has frayed after 13 months and it is now making sparks when I plug it in. I do not wish to spend $80 on a brand new apple charger. Does anybody know of any other chargers that don't have to be apple that I can get for cheaper? Thanks!
