I went to Nathan Burton comedy magic show couple weeks ago and I really enjoyed it. I was never a fan of "America's got talent," but boy, he was entertaining. He had great stunts and magic tricks (yes, bit cheesy, but come on, we're at Vegas). He also told a very sentimental story about his childhood and his mother (and his mother was actually there at the show), which touched my heart very much.
I would definately recommend his show!!!! Definately better than some sneezy comedy or hypnitism show.
