Hey guys, my Quad is coming in on this upcoming Tuesday and i'm going to buy some Ram for it. Currently I'm battling between MacSales.com and 18004Memory.com. I'm buying 4GB's of RAM. 18004Memory.com: $348.95/Fed-Ex overnight/4GB RAM/Generic Brand MacSales.com: $452.00/DHL Overnight/4GB RAM/Samsung Brand How reliable is this "Generic" RAM from 18004MEMORY.com? After Macsales, i looked at Crucial.com, they were like $600+, so these are the two lowest i've seen. Does anyone have any experience with either company?
