When looking for a treadmill, I went looking at the local Walmart. I found a treadmill that wouldn't break the bank but would have a wife range of features. The Image 15.0 R looked like the treadmill for me. What I first noticed and liked was the fact that it cost under $500 before taxes. The next thing was that the treadmill could fold upright and not take up alot of space in my basement when it wasn't being used.
Built into the control center is a speed with three different speed ranges to keep you cool while, you run or walk. There is a quick touch 1.5-10% incline button. It goes 0-10 MPH. Has a 275 lb weight capacity. 2.5 HP Motor. It also has a led screen that keeps track of speed, time, distances, pulse and calaroies. It also has a power on off key that you can attach to yourself to in case you fall off or something else happens and it will shut down the machine. A great safety feature!
It may not be the fanciest treadmill out there, but it has enough options and price point that you can't go wrong with it!
