Hey, so I'm looking to get an iMac, but a refurbished one ( they apparently are JUST as great as a new one without the fancy box) So I record my own music, edit a few vids and do school work. What iMac should I get, a refurbished 20" 2.66 GHZ iMac http://store.apple.com/us/product/FB417L... , a 24" 2.8 GHZ iMac http://store.apple.com/us/product/FB325L... , a 24" 2.93 GHZ iMac http://store.apple.com/us/product/FB419L... , or a 24" 3.06 GHZ iMac http://store.apple.com/us/product/FB398L... ?? P.S. Remember that I'll be using it to create/record music/songs with garageband, edit some vids and pics, school stuff, and when the Sims 3 comes out, that ( I LOVE THE SIMS....I just like making the people die!! (its a weird thing that I have...) P.S.S...if a refurb is a bad idea, PLEASE tell me!! THANKS everyone!
