Near the low end of the Star Trac line if you can call it low-end. A very high quality machine. Some of the components are lightened up a bit from the high end models but they still would beat the components silly on a home machine.
With the huge increases in prices on many competitive home units, the Star Trac commercial units are now a viable option for your home. The great thing is that they are really focusing on the consumer and seem to be getting it figured out. Keep in mind, these aren't as quiet as home units but you get commercial quality at a commercial price. They aren't the lowest cost treadmills on the market but you get a great machine backed up by an innovative company.
