Become a MacRumors Supporter for $50/year with no ads, ability to filter front page stories, and private forums.
And I have to chip in with my standard advice.

I recommend you look for a reputable dealer who tests and guarantees compatibility with your model Mac, offers a lifetime warranty, and a no cost (no restocking, no shipping) return if it doesn't work.

USA vendors that MR readers most often recommend are Crucial (use the link above so MR makes a couple of cents), OWC (MacSales) and Data Memory Systems
