I'm looking to buy a treadmill, and I'm a little confused. I'm just looking to get in shape, and I currently don't run, so I don't need anything really fancy. I went to a Sears and looked around, and they had Nordictrac and Pro-form treadmills, ranging from $400 to almost $2000. I figured around $900 would get a pretty decent setup. But when I looked at review sites, they all pretty much said a good setup starts at $2000, and the cheaper models are suited more to walking than running. So I kinda figured that I must be looking at the wrong reviews, I'm sure $900 will get something decent, but could anymore maybe clue me in as to what to look for?
