Well, I saw the eMotion rollers and am torn. They are $700!!! But the reviews are fantastic. I use it enough to justify the cost (sort of) if it makes a big difference.
I am turning my upstairs den into a workout room, mainly because I am starting Shaun T.s insanity program as well as moving the biking inside for the winter following the Livestrong Challenge in three weeks. I have a new riding friend who is a professional cyclist...I am going to have to up the ante a bit here.
