The folding treadmill version of the value machine for SportsArt. We would go with the Sole foldup and save a few hundred but this is a high quality machine for the money.
The warranty on the SportsArt TR20f is mediocre. Labor is covered for 1 year, electronics are covered for 3 years, parts are covered for 5 years, the motor is covered for 10 years, and the frame is covered for life. When you are spending this much money on a treadmill, you should be getting a better warranty.
