Of course depends on your budget. If you are looking for a residential style treadmill (non-commercial) then I have had good customer ***** with Horizon treadmills (Johnson Fitness). Specifically, the T202. Usually under $800. Good warranty too. If you prefer less impact you may consider an elliptical/cross trainer. Hope you find what you need!

It's more practical to join a gym than to purchase a treadmill.
