I am planning (http://forums.applenova.com/showthread.php?p=260916#post260916) to buy a 1GB RAM stick for my Powerbook. And so of course I do my research...
Buying RAM from Apple would be pretty silly. Sticks of RAM don't take on magical properties just because Apple sells it, but they do magically double in price.
As for where to get it in the UK: I bought it from Crucial and had no problems. However, be aware that although Crucial makes high-quality memory, their UK website employs dirty tricks to encourage Apple customers to pay more than they should. Try this: go to Crucial's UK website and use their Memory Adviser Tool to show you the options available for the 1.2 GHz G4 iBook (my computer). The 512 MB module costs £60.22 (excluding VAT). Now clear your cookies and manually navigate to the DDR 200-pin SODIMM choices. You will see that the EXACT SAME module now costs a much more reasonable £35.58.

This is a common perception that is true in most cases. But not in others. If you have one of three models of Aluminium PowerBook G4 15", aCrucial DDR PC2700 CL=2.5 UNBUFFERED NON-ECC DDR333 2.5V 128Meg x 64 RAM stick is not the same as a Crucial DDR PC2700 CL=2.5 UNBUFFERED NON-ECC DDR333 2.5V 128Meg x 64 that is Guaranteed CompatibleThe first is available for £95.97 (via eBuyer - limited availability only). This module will work in all PowerBook G4 Aluminum Models (12in, 15in, & 17in) EXCEPT the Bus Slewing models. The second is available for £130.41. Let me explain:

As of this writing, the following is a list of the DDR SDRAM Component ICs used in the DIMMs that ship with PowerBooks and iBooks that use Memory bus slewing. (This is subject to change at any time.)
Samsung - K4H560838E, Hynix - HY5DU121622AT, Micron - MT46V16M16
