Commercial model. We were able to find one on Craigslist for $800. It had been in a gym. After that it was refurbished and sold to someone to use in their home. They used it some, but not much. So for very cheap we bought an awesome refurbished Precor. I love it. It inclines and you can change the resistance. It can be a little loud for nap time when you use the incline. But it is so much better then the Nordic track we had before.
On the Nordic track We had to replace 3 wheels and have my dad weld it 2x before my husband convinced me I would love the precor more. And it really is great. However, since it is a commercial model, you can't save custom work outs. Only drawback so far. Oh and if you stop to type a post on Cougarboard for more than about 3 minutes it resets. But those are small drawbacks.
