Hi H.! I have to say that I don't recommend ANY treadmill.
Do you have any experience with Ellipticals? I have a NordicTrak Elliptical and I LOVE it! I used a treadmill for a couple of years before I made the switch and I can't say enough about how much better an elliptical is for your body!
An elliptical works all of your body instead of just doing a walking motion. I have found that I have more endurance on the elliptical and I enjoy exercising more. Plus, it's quieter as there is no motor.
If you are sold on getting a treadmill than I hope you find one you like! happy excercising!
