Make sure whatever recommendation you receive that you are able to go to a store and try it first. My friends and I all like different ones for different reasons as my leg stride is longer then some and I would hit the front of shorter ones. Some would also cause me back pain because the rails were too short. Look for your comfort and then read reviews on durability. Most stores these days will deliver and set up either free or small fee. With one exception sears at least the delivery charge quoted yesterday for a delivery added 69.99 to a purchase....seemed a bit steep.
