Thanks alienex for this thread and grapes911 for the Datamem suggestion. I usually just buy Crucial, but they're out of stock. Just ordered a 1GB from Datamem to complement the 1GB stick in the 1.83 MBP, hopefully it'll work just as well as Crucial.
Also, alienex I'd stick to buying 1GB sticks, 512MB sticks occupy valuable space should you wish to upgrade later. I have not found the matching sticks idea to have much weight, especially compared to upping your total RAM.
