Purchased from Sears on January 3, 2000. I was 56 at the time and used Mountain Trail program five days a week. Replaced walking belt on August 6, 2004. Continued to operate Mountain Trail program five days a week. Replaced walkiing belt again on April 4, 2008. Motor died this morning - June 13, 2008. I think I got my money's worth. Will probably buy another NordicTrack and hope to outlive it.
