Trying to decide if I can justify going with 3 gigs vs 2 in a new MBP. Crucial is charging over $1000. Apple has it for $750, but only seems to sell it as a CTO, not ala carte. Newegg has one for $625. http://www.newegg.com/Product/Product.asp?Item=N82E16820208083 OWC has Samsung memory for $639. Anyone have any feedback about Transcend or other deals on the ram?
