If you're looking for pure quality in terms of design and manufacture take a look at a PaceMaster treadmill. Founded in the 60s by the renowned Bill Staub, PaceMaster treadmills have a reputation as being the best. The PaceMaster Gold Elite comes with a 3 hp continuous duty McMillan motor and a maximum speed of 12 mph. So well put together is this machine, it can handle a pay load of 400 lbs. The incline goes from 0 to 15% with 0.5% inclinations.
So confident is the company about the Gold Elite that is comes with a lifetime warranty on the frame, with 12 years on the motor and a 5 year parts and 1 year labor warranty. It's unheard of for anyone else to have a warranty on the motor for this length of time.
