After reading reviews and threads on the Skier's Edge (retail $2200+) and the Pro Fitter 3D Cross Trainer ($599), I decided the Pro Fitter was the better machine for my needs. I ski and figure skate and the Pro Fitter has benefits over the Skier's Edge for me including greater proprioception and ankle strength training - the foot pads are more independent than the Skier's Edge - and there are many more exercises that can be done with the Pro Fitter.
I received the Pro Fitter yesterday and found myself not wanting to get off it! So much fun. I made a video of the unboxing and first steps on the Pro Fitter for those of you who are interested in this training machine.
