I saw his show in Vegas about 3 years back, and it was great. He's an awesome performer, and he somehow manages to update his acts to match the current styles in magic. Definitely worth seeing before you die... or quit magic.
I saw his show recently when he came to London, Ontario...astounding. Lottery was one of my favourites from the show, as it has so many parts to it, each more amazing than the last. I can't recommend this show enough, it was brilliant. Wherever he ends up after his tour (back in Vegas, I'm guessing), I'll definitely go see him again (and if he does end up back in Vegas, I'll be sure to see Lance Burton and Penn and Teller, as well...MAYBE Criss Angel, if the Cirque show improves drastically).
