Gazelle sucked for me, Total Gym was ok, if you have good shoulders and I bought a Treadclimber, that was the biggest waste of money and I'm still paying for it. If you are 5'2" or shorter, don't bother. The treads are spaced too far apart on the thing for a short person to walk normally without looking like they have a load in the pants and it hurts your hips when you have to space your legs that far apart to walk. They don't tell you that when you buy it.
