I'm kinda loving the Step Mill right now at the Y but wow, is it hard! I was actually really proud of myself that I managed a full 30 min on Wednesday morning especially because it requires a lot more concentration on my part, say than running or the elliptical, because if I start to zone out, I tend to miss a step and get all tripped up!
