I am in metro-west Boston. I have a Skiers Edge that I no longer use as I am using my indoor smart bike trainer in the winter. I find that lots of road biking, gravel rides, and a good set of core exercises and stretching prepares me well for the ski season. Before I was into the biking - I used the Skiers Edge all year and found it to be great preparation for the ski season. Any way, my Skiers Edge is an S4 that was upgraded to the QS5. I have the mogul platform, slope simulator, the “coach’s bar” attachment, and the upper body exercise attachment, along with a spare set of power bands.
I am willing to part with all of this for a price as long as you can pick it up. The coach’s bar is removable so that the skier’s edge can be easily picked up by 2 people and moved. The QS5 is much quieter than the old S4
