Crucial and OWC have kits for 3 or 4 dollars more. Just buy from a retailer so it's easy to exchange in case you have trouble with it.
 
Newegg also has crucial memory at $58 plus shipping, it only ends up being a couple bucks more. I would definitely deal with a company rather than someone selling no-name memory on ebay. Here's a link to Newegg with the crucial memory.

This is from ebay, most people on these forums always recommend crucial, well i found this on ebay, should i trust this or just go with crucial for a extra few dollars? :confused:

thanks for the advice

I have purchased memory from these folks. Has always worked okay for me, but I agree with others here. Buy from OWC. Lifetime warranty, and good prices.
