from my hunting, this is the cheapest i've found. gonna buy me two sticks today. FutureShop, TigerD, NCIX, etc. http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=3164196&CatId=1726 just wanted to confirm this will work. my only concern is that it's listed as PC5400, whereas the tech specs on the new MBP (same as old i think) list they use PC5300. I'm pretty sure they'll work, just would appreciate if any kind sir/madam would confirm TY!
