Stick with the 2900 model and buy a separate TV if you like this one. Nordictrack has come a long way in quality and slowly but surely, they are approaching the $2000 price point with some winning treadmills. I'm not sure if everyone is watching but we are.
TV treads still have a ways to go on average and this one is no exception. We would save our money on the extra TV add-on and get a LCD screen to mount on your wall. It won't take the beating that the treadmill gets.
