well, the elliptical is a gimmick - its not really a natural human movement.
walk even more, DANCE!, hike, run, sprint or jog - with proper form, with minimal footwear or barefoot. slowly relearn proper alignment and coordination. save your money to buy high quality food, a good jumprope, acupuncture, etc.
if you really want to lose weight and gain healthy muscle, short burst high intensity interval training will work better than long slow cardio.
