NordicTrack is essentially telling you what a warranty is worth with this one. Since they are using a common warranty found in specialty stores, you know a couple of hundred is tacked onto the tag. The difference is that I'm pretty certain NordicTrack will be around in 10 years to provide the warranty. You don't know with many of the stores today.
With the upgrade in the motor from the 7000 model, this one is worth considering, especially if you can find it on sale. It is hard to believe that Icon is producing competitive products in the $2k range but you had better believe it!
