We have a heavy-duty Nordic Track C900i Treadmill to pass along. It works fine. It was bought in 2014 for $900 (on sale) and was just serviced. It can handle a user up to 350 pounds. Here's the catch: it is VERY LARGE AND HEAVY, and you must bring a truck and some able-bodied help to wrestle it out of our sunroom. Would prefer to schedule pickup for a weekend. Please state when you can pick it up.
