I noticed today the Apple added some (now) older MBP models to its refurb section. Initially, I was thinking of buying on Craigslist/eBay, but the refurb prices are close enough that I'm going to buy through the store. I'm choosing between three versions, and need help deciding. (They're all 15.4 inches): - 2.53ghz for $1350: http://store.apple.com/us/product/FC118LL/A?mco=MTA4MzI1OTk - 2.4ghz for $1299: http://store.apple.com/us/product/FB470LL/A?mco=MTA4MzI1NTA - 2.66ghz for $1530: http://store.apple.com/us/product/FB985LL/A?mco=MTA4MzI2Nzk I'm pretty sure I'll pay the extra $50 to get the 2.53ghz model (unless you say it's not worth it). But what do you think between the 2.53 and 2.66ghz models? And, to make sure, these are good deals right?
