The headphone jack on my macbook has a piece of a headphone plug stuck inside. I've tried to put a drop of superglue on the remaining piece of the headphones and put it back together, but it didn't come out. Anyway, I was thinking, if I could find a replacement for the jack on the cheap, i'd be able to replace it myself. Problem is I'm not sure where to look for the replacement. Are those jacks standardized? Where can I order one? I've looked into finding a broken motherboard on ebay, but they seem to go for over $100. Any help will be appreciated..
