I am a fan of Penn and Teller. Despite not being into magic in any way, and not someone who generally cares about what's on TV, I watch their current show when I can.
They are about as "real deal" as you can get, despite the schtick. Street magicians from the start to their own theatre in Vegas, and still consistent and creative. At this point it is likely they don't do it because they have to, they do it because they still want to. With the new show being trying to have them unravel someone's trick, with the odds stacked greatly against the magician, it's pretty obvious they've almost "seen it all".
It also gave me a glimpse on how secretive the magician community is. Since people earn a living selling required gimmicks or instructions on how to perform specific tricks, it is completely unacceptable to discuss how things are done. For the really puzzling ones on the show, if you go online to try to find the answers, you'll often find others asking the same thing, and the accompanying wall of silence. Even more so on forums dedicated specifically to magicians. You're likely to find a large discussion, usually with links to the official store for the trick, and zero answers. To do that would be breaking the magician's code, and apparently, you don't break the code.
