The NordicTrack Classic Pro Ski Machine has been around for over 45 years and you don't see many used units for sale because, while many other exercise machines have come and gone, NordicTrack has proven to be one of the best exercise machines for a great full body workout including cardio and people seldom sell them. It folds down for easy storage. When I bought mine it cost over $800. and they are about $1350. today. I'm only selling it due to health and age. Please see the weblink in this ad for further info. This unit is in excellent condition and you can have it for $175. Please call 250 722 3917
