I want to buy another 512 MB of RAM for my Powerbook so I checked out crucial.com. The price for a 512 MB chip for my Powerbook is $139.99, but if I look for 512 MB of RAM for any other 12", 15", or 17" Powerbook (excluding the Ti book), the RAM is priced at ~$107. I don't want to spend an extra $30 some just because of the specific model I have. Has anyone bought crucial RAM for their 1.25 GHz 15" Powerbook other than the "recommended" RAM? Please let me know, and if you could include the model number of the RAM, that would be awesome. Thanks.
