Anyone here have either one? I'm looking for some feedback. We're considering the x22i incline trainer from nordictrack to double as a treadmill, or the Peloton because it's easier on the knees than running. After some quick research it is clear both require a monthly charge for training classes. This is a nice feature but kind of a turn off after spending the money on the machine itself. Are the classes worth it? How's the build quality? Any info is appreciated.
