You also get compatible ram from
here or from
here
I've dealt with 18004memeory.com and have had good experinces with the memory they sell. Also I just did the Mini RAM upgrade lastnight to the 1 gig. It wasn't too hard to do you just have to be VERY careful and also have the right tool to do it. I went to sears and got the proper putty knife as listed in the service Manual. 1.5 inch 38mm thickness.
