MacBook Pro RAM config

[Edward Arrowsmith]

I am waiting for the next iteration of the 15" MacBook Pro. Its  
getting expensive as I add maximum RAM and AppleCare Protection Plan  
so in trying to cut the cost a bit I thought purchasing non-Apple RAM  
would help.

Has anyone maxed out a MacBook Pro with non-Apple RAM? If so what  
brand, how much and how is it? What are the intricacies with RAM in  
the MacBook Pros? I heard it can only be in 1Gb modules or something.  
Any related info would be greatly appreciated.

Thanks and best wishes
