In looking at other reviews, the above treadmills seem to be good options. I typically run 3 miles at 6-7 mph 4-5 times a week. I do not really need the display graphics or extras ( I watch tv) and typically manually put in pace changes and do not use the different options. I would prefer a sturdy, long lasting model with good cushion to limit pounding of joints. Any recommendations? from past posts-it appears nordic track is limited by it's customer service department-would that be the main limitations to the 1750? I have a nordic track but not had experience with sole products. And either way-you do recommend the extended warranty-correct? thanks for input and suggestions.
