I am thinking about upgrading my 17" Macbook Pro from 2gb of ram to 4gb of ram. I have been looking at prices and it seems that Kingston's ram is much more expensive than anyone else's. Is there a reason why? a 4 gb kit (2x2 gb) from Kingston is $110-150 and on Crucial it is $90. Is the ram from Kingston that much better? 
Also if anyone has any other recommendations for places to get ram that would be great
