Good components in key areas with cheaper parts where you can afford to get away with it. It is near the top of the class in the $1000 range.
The warranty on the NordicTrack T8.0 is disappointing. Labor is covered for 1 year, parts are covered for 2 years, and the motor and frame are covered for life. You hope for better coverage than this when you shop for a treadmill because it really doesn't display any faith in this machine on the part of the manufacturer.
