We've had a relatively inexpensive Proform XL Crosswalk ($350) treadmill for several yrs and its given us no problems other than 2 AA batteries to run the data panel. To me, the most imp features are the clock, the choice of intensity (warm up/turtle pace to an aerobic/performance level), the incline adjustment, knowing how many calories you've burned, and the length of the stride panel belt itself. All those other bells and whistles are just that, really inconsequential. A huge investment is not necessary just getting on it, turning on music or tv w/remote ctrl, and staying on it and keeping your heart rate up regardless the length of time is better than sitting on the couch. Ellipticals I cant speak to never having tried one. It was however included as part of therapy for my daughter who had a severe broken leg. So it really helped with strengthening the weakened muscles. Good luck to you.
