I am look at one of two treadmills to buy and am looking for spec info to compare. The units are:

Nordic Track Powertread PT 5.5 and
Nordic Track Powertread PT 1750

Does anyone have any specs on these. Is one better than the other?

I have called customer service at Nordic Track, and searched the internet to no avail. Does any one have either one of these units or a spec summary you could send?

Thanks
Chris
