I have one as well and love it. I actually use it unlike my treadmill.

BUT I do strongly suggest if you buy one get the one that you can change the level of workout. I didn't, I bought the $100 one and now wish I hadn't. I don't feel like I'm going to be able to always use it, eventually It won't give me a good enough work out.

PS Go to Walmart, or Kmart and look at them. They might not be the best price out there but that way you can see what is available. I believe you can even see them online if you go to their websites.
