It is a proform 510E and has 18 built in workout apps, dual grip heart rate monitor, ifit compatible, music port for iPod/iPhone, different degree inclines and resistance levels. Brand new only been used a couple of times, No scratches whatsoever no wear on the buttons or anything. I would love to keep it but I need the extra space now. It's originally $800 but I would like to get $650 or so for it. Price is NOT set. EMAIL me if interested, k_staggs1 @aol.com.
