Hi Guys, We're looking at treadmills. We're in a small town, and the local rec center only has 2, and they're jammed. (they also have 2 nice ellipticals, but they don't feel comfortable, and some recumbent bikes, but I really like treadmills, especially in winter.) We've been looking at Sears' web site, since they seem to be the treadmill dealer! Does anyone have any advice on extended warranty plans (do treadmills die often?) and brand/level advice? I'm trying to not break a grand. Actually, hopefully much less. But it's hard to compare apples to oranges if one shows peak hp and another continous hp (Amplifier ratings, anyone?) Are used treadmills an option, or are they likely to be burnt and worn out? Thanks!
