Err I'm not sure which forum I should post this so please correct me if I place this in the wrong place... I'm a runner, I compete in marathons... Currently, I'm in a dilemma of choosing between these two treadmills for my home gym: http://www.treadmills411.com/1800treadmills/Trupace_M120_Treadmill.html or http://www.treadmills411.com/Proform/Proform_850_T.html They both look very sweet and I really can't make up my mind. Any suggestions? Your suggestions would really be appreciated. Thanks!
