If you plan to use it regularly, you're gonna need to spend some coin. The cheap treadmills are garbage... go Precor. It's pricey - but if you're using it regularly - it will last a really long time and can handle the wear and tear very well... that's why all the gyms have it. I believe Precor sells commercial versions of their treadmills (for gyms) and less pricier residential versions of their commercial versions for homes. I'd still go with the commercial version... but I run on a treadmill every day - so I'd need something that could withstand the heavy usage.
