I would like to upgrade my memory too. I have a 2.5ghz MBP with 2 gigs of ram. I was wondering if I can just buy a 2 gig stick from crucial and put it in my mac. Will the lat 5 2 gig stick from crucial play nice with the 2 gig already in my computer? Thx.

What you have in your MBP is 2x1gb chips. To get to 4gb you will need to remove both chips and put in 2x2gb chips.
 
I have a macbook pro and wanted to get some ram for it. I found this ram:

Crucial 4GB (2x2GB) DDR2-667 PC2-5300 Notebook (SODIMM) Memory

Will be compatible with the mac, and how good this ram?

Thanks In advance

That would work fine. Crucial is well respected by people on this forum (and other mac users).
 
And pay 3 to 4 times more? I don't think so.

The crucial Ram you picked out is an excellent choice. I see they have it on sale at Newegg for $76, and free shipping.

Correction: Apple wants $400 for 4gb (2x2) of Ram. That is nuts. 5.26 times higher.

no just about thrice as much. 4gb is 200 dollars. i bought it through apple.
 
Except those are out of stock. :(

Anything else you could recommend?
How bout this? http://eshop.macsales.com/item/Other World Computing/53C4DDR2P4GB/

Also, how does the memory from Newegg / OWC compare to the memory Apple sells?

As has been posted many times:
Understanding Intel Mac RAM
Buying RAM

Apple uses RAM they buy from Samsung, Hynix, Micron and Elpida just like the reputable third party RAM suppliers use.

There will be no performance difference between 2 brands of RAM that are tested and 100% compatible. (with the exception of the more expensive CAS Latency 4 RAM from OWC and Corsair, which gain about 1%)

OWC, DMS, Crucial and other RAM companies that support Macintosh are the best bet. NewEgg and Fry's and other discounters don't provide support and leave it up to you to choose the correct RAM. This can work for you if you know what you need and spot a sale, but watch for shipping and restocking charges if you get RAM that doesn't work.
