meh, for that price, you can't go wrong. Also, doing a replacement on backlights is a BIG thing. Very hard to do, so if you aren't in for spending a few hours doing it, go ahead. I dread doing them myself, as there is a HUGE risk for cracking the LCD.

Second: you will need TWO of the CCFL's to do it. Screens on the older Powerbooks usually take them in sets of twos. Newer displays for Desktop LCDs take them in sets of 4s. So in a modern display, there is two on the bottom, two on the top.

Older Powerbooks are like One on the bottom, one on the top.
