(search around, I should know, I've been railed for my post on RAM)
But, short and sweet: I just put in my 512 that I got from macsolutions.com into my Ti, and it's working wonders. Only cost me about $340 after shipping to Hawaii, I think it was $321 before that, and it got here in 2 days. My advice is to stay away from 18004memory, and other people will say to avoid memorytogo (like I said, search the forums), but everyone has differing opinions on all of them...
