I have a pbook with the stock 512 RAM. I want to add more, but Apple RAM is very expensive, especially here in SA. 256mb costs approx $ 210 (R1350) 512mb costs approx $ 410 (R2640) I think that price is crazy. Or is it just me? What other makes can i fit into my Pbook, and where can I find it? (idealy in the UK or the US) Do you think its safe to post RAM internationaly?
