Im soon going to buy a powerbook, after mwsf. I will probably buy bto, and upgrade the ram myself. How much does a stick of 1gb ram usually cost? Does it make a huge difference on the manufacturer? Would it be better to get a 1 gb stick from a lower manufacturer than a 512 stick from a good manufacturer? Also, what is the markup on ram, because i can buy it from bestbuy where i get it for almost their cost, so is the markup a lot? Hopefully it is lol. I saw people saying how a stick of 1gb only cost them like 150, but everywhere ive looked is like 300.
