My 12" powerbook's power adapter is dying. The cable that connects to the laptop is making a funny noise right where it is connected to the transformer. I'm assuming that internally there are some bad wires. Anyways, I went to buy a new one and I discovered that not only are they $80 but they have gotten terrible ratings. People really really hate the ones they have bought. I dont' want to buy a new adapter only to have it break in a month. What do you guys suggest? Shoudl I just buy the apple one or should I try a 3rd party one? Has anyone bought a 3rd party one?
