Only buy clipshift if you realize that you will not be satisfied until 6 months into it XD.
Personally, I bought the dvd, I loved it, and then I felt jipped that I paid so much for one move, that I couldn't perform yet. Six months later, I had the move down, still noisy though. Now almost a year and a half later, I feel like I have mastered it to my desire. It was worth the 40 dollars just to hear David Williamson say "Show that to Charlie Fry" at magic live.
