The new version of the Audiostrider 990 is not worth $1500, but don't worry, they'll be selling this for $999 in no time.
The Audiostrider990 is a solid elliptical for $899. It has good stride adjustability, and excellent motion and feel, good design and Ok quality of construction. The only real downside of this machine is if you need to contact NordicTrack customer service. You may have to wait a considerable length of time and good luck finding a technician that actually knows what they are doing.
