Precor is well known in the fitness industry for manufacturing high quality equipment, and this unit is no exception. The 9.31 treadmill is quiet, solid, and well engineered. However, this unit is not feature rich and it is not well priced. Generally priced around $4,000, this unit is a hard sell for us. For this price, you could easily find the same quality treadmill with more features from a different manufacturer. In fact, you could likely find a less expensive unit from a manufacturer like Smooth Fitness that is more feature rich with a better warranty.

Overall, if you don't mind the high price tag, and want a no frills treadmill that is high quality, go for the 9.31 from Precor. If you want a little more bang for your buck, go with a different manufacturer.
