I wanted to buy an elliptical for home, so I shopped around and couldn't find one, then compared to the StarTrac ones at the gym. So I tracked down a place that sold second hand StarTrac ellipticals exactly like the one (commercial quality) I was using at the gym and I bought one for AU$2,500 (in 2007).
I spent another $1,000 to make it run a little easier, and it is simply the best. I love it. Couldn't be happier with it. I think new they are about AU$8,000 but this is as good as new to me.
I've had it for three years now and have not had a single problem. Go StarTrac!
