The most expensive Xterra and quite a good machine considering the price point. With that said it has a tough time when you compare it with the NordicTrack C1650. Missing many of the extra electronic features you get in an Icon machine.
If you want the best treadmill, get a NordicTrack or Proform. Dyaco is so far behind the technology that Johnson and Icon are putting in their machines that it is almost laughable. While Dyaco builds a quality unit, they don't build anything close to a system that can keep you from getting bored quickly nor do they have high quality interfaces. We know that mechanical switches like Dyaco uses are very reliable but they are also cheap and feel cheap.
