Before buying anything have a close look at the motherboard manual. It will tell you what kind (type, speed) of RAM you need to buy, and what configurations of different sticks are possible. It's not unlikely at all you can stick the correct type of 256 MB stick next to the existing, but you'd better check.
I looked on google for prices, and found one for $60. But I'm sure Bob Proffitt will tell you much more on where to buy for what price.

alright first of all forgive me for me stupidity because when it comes to computer hardware, i am a newbie. anyway i am going to purcase starwars galaxies and i meet all the system reqs (most i just barely meet). I have 256mb ram which is required but i hear it runs horribly with it and i need to have 512mb. do i just need to buy another 256mb ram and put that in there with the other or what? also how much you think itd cost for 256mb pc133?
