Yeah it is pretty good I have it. I like the body builder one but it's a cheap remake of the Nordik Track. I'd go with the one with that has a longer warranty.
Although NordicTrack treadmills are great they are expensive. I bought a golds gym brand treadmil from walmart for a great price and it has been working beautifully for two years now.
I personally like Nautilus products better than NordicTrack. I just think they are built better and last longer. Nautilus is also a bigger marketed brand, and they have a name to live up to.
