Just keep your eye on apple's refurb site. I did, and when a 2 ghz came along, I snagged it. I paid 1999.00 for my 2ghz a little over a year ago. I see the 2.66 ghz is 1999.00 now. Haven't seen the 2ghz in awhile. I would suggest you get a refurb from apple as you will get a 1 year warrenty with it and you can still get apple care if you want. I am planning on upgrading mine with two quad core chips soon. Good luck.
