Horizon T101 Treadmill I bought this tread. I've put a lot of miles on it, I'm currently walking 9 miles a day (I'm retired). I split it up 3 times a day and it works for me. I do usually 3.5 mph at a #4 incline. Now you can buy dozens of treads, but you won't have the customer service this company has! Nothing short of OUTSTANDING! I have just about smoked up the running belt after a year (a couple weeks over warranty). I contacted the company about purchasing another belt. THEIR SENDING ME A FREE BELT (value of $129 not including shipping/handling/etc). Simply a great company THAT APPRECIATES THEIR CUSTOMERS with experienced CSR'S and fast ONE DAY e-mail replies. I wouldn't hesitate to recommend HORIZON to any of my family/friends. Don't hesitate to buy this treadmill!
