I have had a precor eliptical for about 2 years. I love it. I seem to have problems with exercise programs--like developing a horrible skin allergy to clorine after swimming every day for almost 3 years, ended up with heel spurs with a treadmil, bad knees with a stairclimber and the storry goes on. Anyway it seems that an eliptical must be easy on the joints etc because I've done that for years and never had a problem. I used a NorticTrack for several years--it was ok but needed repairs pretty regularly. The Precor hasn't given a bit of problem and I use it daily along with my two teens who run track, Xcountry and use it all winter. Expensive, but a great machine.
