Shinji Saito and the State of the Art in Yo-Yos
It's too bad that you can't find his 2005 World Yo Yo championship performance on Google Video anymore (I don't know what happened to it), but this kid is amazing. He can do things with yo-yos that you wouldn't believe, including flips while he has two yo-yos circling every which way. It's like a circus with Yo-Yos.

Anyhow, I'm only posting this because I just dusted off an old wooden yo-yo and have been fiddling with it a bit, which piqued my interest in the state of the art. Well guess what -- it's pretty normal for a 'pro' yo-yo to cost $40 (and up), and there are even $100 (and up!) yo-yos out there.
Well, that sounds a bit crazy until you hear about the tricks the kids are doing these days. First of all, there's a whole new set of aerial yo-yo tricks that involve pulling the yo-yo off the string like a top, and then restringing it in mid air! These are called "stringless" tricks. Tricks with two yo-yos are so common place that there's even a competetive division for it. And then there's a yo-yo that some guy can make sleep for over two minutes! Now that's a crazy yo-yo.
Almost all the competitive yo-yos have some sort of transaxle and ball-bearing system -- which makes it difficult to wind them for beginners, but makes them sleep like dogs. They are weighted at the rim for longer sleep times, and most have some sort of new-fangled friction device in the gap that assists in rewinding the yo-yo in mid trick. These are not your old duncan yo-yo. Anyhow, I wonder if yo-yos, which are now so high tech, can ever be cool. My old wooden one (a Tom Kuhn "Recreation Device One"), which does have a transaxle and ball bearing system, is pretty fun.
