David didn't use the elevator , he used the balducci for one version and then camera work for another. The elevator is good, but does take some time to practice. You have to practice balancing. Once mastered it's very good. I think it's worth the money. One thing you should know is that you have to perform it with a jacket or un-tucked shirt to end clean.
i would just like to say that when reading this you have just made me think of a brand new idea for a levitation
i cant wait to start working on it thanks
