Another reason people may be disappointed if they were to shell out the money for the CA levitation is the way it's presented on TV vs the way it's presented in reality. It's recommended to only do it for one person at a time. On the tv show, he has people right to his right front, who go on clapping as if they've just been amazed. I suspect (and it's only a suspicion since I don't know the exact method he uses) that those people are either "in on it" with CA, or are just willing to clap as a wink at those who are being fooled behind him.
