I purchased all three DVD's, and I'm certainly glad I did. For me, the key thing to remember is ENDLESS, THOUGHTLESS PRACTICE. What do I mean? Well, take a deck with you wherever you go, whether it's school, work, dinner, or whatever. Whenever you're idle just grab some cards and start doing fans, productions, or any other flourishes you want. This kind of practice encourages your hands to "learn" the moves so well that you can do them without concentrating at all. I swear, most of my practice hours have come while sitting in front of the TV...I start playing with a deck of cards without even realizing it.
Jeff certainly is a good teacher, and his routines are delightful.
