Not a fan of ortho belts but Horizon does a decent job. At $2000, there are other choices we would pick. If you can find it for a discount, this model is a good choice but I would want a serious discount.
A great looking treadmill but the ortho belt gives us cause for concern, especially since they claim a maintenance-free drive system. This is the old formula for replacing parts down the road unless you ignore their claims and maintain the machine.
