I bought a new Nordic track after my last treadmill just decided to quit. I use the treadmill almost everyday. I don't need all the bells and whistles like it has. But I was interested in it having a WIDE belt. I'm a little older, and didn't need the extra chance of falling off, stepping off, etc unintentionally.
I opted for a new one for a couple reasons. I didn't want one that I didn't know the history of......lots of use, a HEAVY user, etc. I never would have thought about the weight of a person until both my grown son and son-in-law tried to use my treadmill (at different times!) and both commented that it seemed to 'stutter' when their foot hit the surface. Both are good size men, but neither huge.
The cost of it was a splurge for me and my husband, but I don't really have other 'vices', so investing in a good 'vice' that I use constantly, was okay by us. And I know from experience that I would use it. If you're not sure it's going to be used as exercise equipment, or a coat hanger.....maybe start with a used one.
I've been using a treadmill for 4 or 5 years. Crazy as it sounds, I'm kinda addicted to it. It's been MAJOR keeping my weight consistent and a good de-stressor after work.
And YES....it was extremely heavy to move into the house !!!!!!!!! We should have enlisted a couple high school guys to help us.
