The Schwinn, at around $750, is a good all-around elliptical for the budget-conscious exerciser. It includes arm handles so you can work the upper body and it also includes 12 workout programs with 8 computer-controlled magnetic resistance levels. What I like about this one is its small profile, perfect if you don't have much space. It also has a longer stride than some ellipticals (18 inches) and articulating foot-plates so you don't have to worry about your feet going numb (a common problem on ellipticals).
The NordicTrack E5Vi has some nice features including arm handles, an adjustable stride (13", 15" or 18"), 16 preset workouts, 12 levels of resistance to choose from and a space saver feature that allows you to roll it into a corner without throwing out your back. It also has a compatible music port for your iPod and a built-in speaker system. At about $599,
the NordicTrack is a great price, especially considering some of the great features included.
