ram upgrade on fall 09 macbook

Hey guys I was looking to upgrade my ram on my macbook (fall 09).. I was wondering what is the best deal for 4 gigs of ram that is under 150$ I was looking online and I've seen some good deals but I dont know which would be the best, and I would like a standpoint from a current mac user.thanks!

In conjuntion with the Feeling's question: is 4 gigs the absolute MAX RAM that will fit in a 13inch MBP 5,5?
