Corsair is good.
Normally I'd tell you not to waste your money on putting "Mac Compatible" RAM in a MB or MBP because while you obviously *can* put it in (if you want to be totally absolutely 100% doubly certain that the RAM will be compatible) the machines take regular old DDR2/667 SODIMMs and just about any stick ought to work, whether it's labeled Mac Compatible or not.
In this case though... there's functionally no cost difference between "regular" PC5300 SODIMMs and "Mac Compatible" PC5300 SODIMMs. So. You might as well get the Mac compatible stuff. And, as I said, Corsair is a good brand. Mushkin is good, Crucial and Kingston are good, PNY, OCZ and Patriot are good as well... Basically just look for something with a lifetime warranty, which is what most decent RAM manufacturers are offering now.
