I have the 2.0GHz white MacBook (MacBook2,1) upgraded to 2GB of RAM. I read the thread saying I can kick it up to 3GB, and I'd like to go that route. The problem is, I've found a lot of options online and the prices are largely different. Can anyone help me find competitively priced RAM from a respectable memory manufacturer (2 x 2GB)? I wouldn't want to end up buying RAM that is more expensive if there's no need. Thanks!
