This is the best ski machine ever made by Nordic Track. It is the Medallist, Anniversary model. It is made of Hardwood and sturdy metals. The ski have adjustable tension, the arms pulley has adjustable tension. The front legs are adjustable. It works like new. The skis have brass tips and ends. It is super deluxe. It comes with a gauge (with another spare gauge). I never used the gauge, but it also comes with a device you can wear for pulse rate, which I never used. Comes with manual , oil lube, wrench, etc.)
