i have always been partial to newegg.com. have purchased ram from there for multiple macs since 2005 and never once had a dud. read reviews on the products before purchase, can save headache to hear from current users. best of luck.
 
Sorry to bump this thread. I just returned from the Apple store and had my logic board replaced and they also said that one of the RAM sticks is defective and they removed it. So now I only have 1GB of memory and I can feel the change.

I'm looking for 4GB of memory. I just need to find a cheap memory that works good. I went to newegg but they sell 4GB for 90$. Is that the normal price for 4GB of RAM? Or should I look someplace else?

EDIT: I found this: link on amazon and I was just wanted to make sure if it would work on my 2.4 Early 2008 MBP. Thanks!

currently got 2x2gb

looking at buying a single 4gb stick. Crucial is giving me crazy rates.

Has anyone bought ram for this machine lately?
 
I would stick with Crucial. In addition to being a top quality product, they also have the best returns policy and customer service. Their customer service is based entirely in the US too, not in India or China or somewhere else. I had a stick fail on me once, and I called them up. No waiting, went straight a competent technical guy (not some stupid low-level person, reading from a script).

I told him I was running Linux, and I had just run memtest86 and it showed errors. When I removed that one stick, memtest86 would run perfectly. Put the one stick back in, and memtest86 shows errors again. He immediately gave me an RMA number to exchange the faulty stick. No jumping through hoops, no downloading stupid diagnostic software and sending them the results, no trial-and-error troubleshooting, and no "sorry we don't support Linux" baloney.

The entire telephone call took under 5 minutes. I received the new replacement stick in 2 days (worked perfectly), and used the container to mail back my bad one.

This was hands-down the best technical support I have ever received on a computer component.
