I usually order from NCIX.com which ships from Vancouver.
For RAM the prices are very competitive on NCIX but there are shipping charges. Still with shipping included I find their prices better than most in TO.
the kingston PC3200 200 pin SO Dimm module should work. The RAM bus speed is faster than what is needed by the ibook which requires PC2100. The faster 3200 will work but at an underclocked speed. Kingston has a lifetime warranty on all its modules and also guarantees that the memory will in ibooks. Usually the retailer will allow you to test it out too. Either take your ibook to the store or just buy it and return it if it is not compatible.
