On a similar topic - looking for some opinions on the Nordic Track EXP 7i treadmill. I have the opportunity to purchase a used 2019 for $800. New retails for around $1099 before tax. The warranty on parts is good until June 2022. The owner “says she only used it for walking” - take that for what it’s worth. Don’t know anything about treadmills so not sure if this is a good deal or not. Help?!
