Hello, I have just bought the new iMac with 4GB ram. I would like to upgrade this to either 12 GB or 16 GB. I have read a lot about RAM on this forum and found that both OWC RAM from http://eshop.macsales.com and RAM from Newegg should be perfect. The prices are tempting but as I live in Europe, I will have to pay a high amount of toll because it is sent from U.S. Does anyone know a reliable seller in the U.K. (or other European countries) with reasonable prices?
