Precor EFX 5.17i

Reviewers say Precor makes high-quality elliptical trainers, but they're very expensive. The Precor EFX 5.17i is an entry-level model that receives good ratings from experts and owners. The Precor EFX 5.17i has 20 resistance levels, a 19-inch stride length and an adjustable ramp. However, this model includes only four workout programs. The biggest complaint, other than price, is that the Precor EFX 5.17i lacks moving arms for an upper-body workout. Still, reviewers say the company offers excellent warranty backing and customer support. It is possible to get a full-body elliptical trainer at a more moderate price: Experts say the Sole E35 (*Est. $1,300) is a good residential-use elliptical and it costs far less.
