Hey, I need buying advice for a 15" Al Powerbook topcase. I'm reconditioning this laptop for family that doesn't have a lot of money but the letters are worn off the keys and the mouse button is sticking. I can't justify spending $150 for the part. I've tried ebay but there doesn't seem to be any used (cheap) ones that guarantee that they work. 1) Does anybody know where I can find a good used topcase? 2) If not, is anybody selling a good, used topcase? Thanks guys.
