On http://www.sunharmony.com (the one I got looks like a distributor's site), they say that they are offering the original Chi Machine -- for $490. You can read testimonials on this site. They warn of fake machines; perhaps that is why they break down so quickly. I did not read through the whole site, but it would appear to have some good information.
It looks like a great way to get exercise; the testimonials mention some very interesting improvements in health.
