We have a Precor home model that is very similar to what is in the gym to which we used to belong. We tried a $500 model from Dick's Sporting Goods but it was awful and the pedals didn't operate smoothly, so we bit the bullet and bought a good one. I'd still use it if I can get me whiplash to calm down. My neck and shoulder hurt too much after bouncing on it. DH and DD use it all the time, though.
