I have had the same problem finding Ram for my PowerBook. There is no real places in Australia to find computer components, besides the overpriced resellers. I have dealt with Harris Technologies (www.ht.com.au), and they seem to have good deals on computer components and other peripherals. Dick Smith Electronics also have a range (not a very good one IMO) but they had ram what works in my PMG4. Can any other Aussies here tell us where they buy their Ram from?
