I have a treadmill that is an older Nordic Track. It is a nice one but everyone tells me that a better excercise machine is the ellipticals.  My hubby’s daughter has one that is a real nice and I tried it once and it is ok but kind of hard for a small person to get it started.  Once I got it to move though it was actually pretty much fun to do and not like excercise at all.  After this Nordic Track wears out I think that I will change excercise machines!
