Why would you pay $100 or more for the same Apple product? Yup, I’m a big fan and advocate of buying Apple Factory Certified Refurbished Macs, iPods, iPads and accessories. Here are four great reasons to buy refurbished — save real money, free shipping, free (after rebate) printer and a full + extendible AppleCare warranty.

• [p] MacBook 2.4GHz, $849 (999)
— 2GB, 250GB, SuperDrive, GeForce 320M

• [c] MacBook Air 1.4 GHz, $849 (999)
— 2GB, 64GB SSD, GeForce 320M

• [p] MacBook Pro 2.4GHz, $899 (1199)
— 4GB, 250GB, SuperDrive, GeForce 320M

• [p] iMac 21.5-inch 3.06GHz, $929 (999)
— 4GB, 500GB, SuperDrive, Radeon HD 4670

[p] previous generation, [c] current generation

My personal favorite in this lot is the $929 iMac. It’s a good value because it has discreet graphics and will play well with Apple’s upcoming Mac OS X Lion.

Again, all Apple Factory Certified Refurbished Macs come with free shipping, free (AR) printer and full + extendible AppleCare warranty. Additionally, portables include a new battery.
