I just bought one of these for what I think is a pretty good price. I think it's about 10 years old and is in great shape.
I have a few questions, I hope I'm not repeating from old threads but I didn't find these specific things addressed in any detail.
1 - how difficult, expensive and worthwhile is it to upgrade it to newer parts? Like S4 swing footpedals.
2 - any tips for how to maximize value that might not be immediately obvious? For example, is it best to turn your upper body to the side to simulate your upper body facing more downhill while your skis and feet face more sideways? (Not sure that makes sense)
3 - has anybody ever looked into wearing ski boots while using these machines? It doesn't seem feasible but I'm wondering if there are accessories or tricks that allow this
