That one looks like a discontinuing product.
Nordic (also know as proform) is currently number 1 in treadmill market
share.
The commercial grade one is: http://www.nordictrack.com/webapp/wcs/stores/servlet/Product_-1
However the true commercial grade treadmill such as lifefitness and matrix
is much better built with a much higher price tag. For normal runners with
interval run bellow 12mph, The difference wont be that much to really
justify the price difference of over $5,000. (unless you intend to keep it
more than 10 years). Most commerical grade treadmills provide life-time
warantee.
Best luck.
