The Proform 850 elliptical with game fit has a lot of features for the money, just wish it didn't wobble so much. The action is smooth and youo can tell the insides are quality. It feels very solid. The only part that is cheaply made is the caseing. It is plastic that is snapped together. It constantly unsnaps and doesn't fir together very well. The stride is around 18 inches. Pretty long and the foot pedals are huge. The motion of the handles is very smooth and slid as well. There is a set of speakers built in. You can attach any mp3 player using the included wires. There is even an apple ipod...
