I want to add one thing to me earlier post. Some are reporting problems with Lifefitness treadmills. I think there is a huge difference between the professional models that many gyms and higher end hotels buy and the models that sell for $3,000 or less, the home models. The current model of treadmill that Lifefitness sells to gyms/hotels is the "Club Series" and the X model is the one without any bells and whistles. I bought it from ABT who is one of the few retailers that will negotiate on major purchases. If I were buying a treadmill today, I would buy either a new Landice L7 or I would buy a refurbished Lifefitness model. Think about it, there must be hundreds of gyms going bankrupt - so it is a great time to buy good, used equipment
