You can order a relatively inexpensive but good treadmill here and pay extra to arrange for delivery and assembly
Horizon Fitness
I had one in Illinois and wish I could fit it here in Florida. I love to watch Netflix, Amazon Prime, etc. while getting my walking in each day.
If you desire a higher end treadmill, I’m sure you can do the same with those companies, like True, etc. I’ve had treadmills most of my adult life and it’s helpful for fighting the weight. They key to consistency for me has been using an iPad or tv to stay entertained while I walk. Sometimes I take slower walks and read while I walk which is also very enjoyable.
