RAM help

I am looking to upgrade the ram of my Macbook.  It is able to support up to 6gb of memory but I am only interested in going from 2 to 4.

What brand of sticks should i look at and does anyone have any other advice?

thanks

have you people ever heard of google? all your answers are there my friend. type: ram for mac and BAM! answers. i'd recommend getting the best deal meaning whatever is cheaper.
