With the $200 price drop it is a better deal but you get cheap - cheap parts for the price.
The warranty on the Proform 585 CS is very poor. Parts and labor are covered for 1 year, the motor is covered for 25 years, and the frame is covered for life. This warranty shows Proform's lack of faith in this model. They don't seem to think it will last long, and we don't either.
