The X6250 is a commercial ellitpical for the home market.
Strengths: Adjustability and quality.
You will probably never need an ellitpical as durable as the X6250, but if you have the urge to overbuy for your home, you can do a lot worse than this machine. While they market this unit for the home, it's primary customer is not you but the average hotel and apartment fitness center. Keep that in mind if you are looking to buy.
