Jordan S. Gruber, founder of the SuperBound® Project and http://Enlightenment.Com, compares the bungee-based Bellicon 44, probably the world's best (and perhaps the most expensive) rebounder, with the 1st-ever alternative bungee-based rebounder, the JumpSport Fitness Trampoline. Conclusion: the Bellicon costs twice as much, but is definitely worth the price.
