Yeah, don't buy from Apple, it's so overpriced
I bought a pair of 1GB sticks from Outpost.com for $159.99 w/ free shipping
These are the spec's
DDR2 2GB PC5300 DUAL SO- 2X1GB SPEED 667MHz
Although I don't see Outpost with the same deal right now (currently $249.99) but keep an eye out, every now and then they have these super sales.
