I'm selling a 2 month old Pro-Form 520zn treadmill. It has iFit technology, google maps, 10 levels of incline with the touch of a button, preset programs, light up screen, built in fan, am ipod plug in spot, and so much more! It's definitely the balls of a treadmill. My Aunt had 2 of them and is moving so that's the reason for selling. Wish I could get better pics but it's folded up in a small room during the move. Asking $500.00 or best offer.
