I bought a Blackburn mag trainer because I wasn't sure I would ride it enough to justify a higher cost. Not too bad, also started doing the spinervals workouts. The really odd thing was that the show featured some elite athletes, yet I was able to keep up! Figured I was in pretty good shape... NOT! Borrowed a friend's Kurt Kinetic, brought me back to reality very quickly. The same workouts were far more difficult, could not keep target cadence in the gear they called for. Even at max resistance, the mag trainer was not close to the more realistic feel of the KK. couldn't really stand up on the Blackburn, no problem on the KK. If I had to buy another, would definitely go with KK.
