At this stage in the game you must take your time, and gather information. Concentrate on the mechanics of the treadmill, rather than its bells and whistles. The most critical components of a treadmill are outlined below. Purchasing your treadmill from a specialty store that specializes in treadmills sales and service will ensure more knowledgeable staff to help you; both before, and after the sale.
Your shopping experience should be as painless as possible. Try to avoid pushy commission based sales personnel. Ask to see if the store you are purchasing from does their own service for the product that they sell. It is always a good idea to purchase from a company that services what they sell versus a third party service provider. Ask how long it takes to get service should you require it.
