Oh man, you should look into it. The yoyo (toy) scene is going through an absolute renaissance. Here's a good video from Wired to get an overview of the hobby.
I'm not much of a collector, but my daily driver is a "MagicYoyo T5 Plus Overlord" I picked up on Amazon. One day I'd like to upgrade to something like the "Monarch."
Sorry about the delayed response, my job is kicking my ass. Here's a link to a video that shows all the different styles of modern play. If you decide you want to dive into the hobby then feel free to pm me. I'll be happy to help.
Iirc Duncan is still pretty solid (and easy to find), though there's a lot of options out there these days.
If you're looking for a more modern entry-level yoyo, I'd personally recommend the Crystal K2. This one comes with a spare "unresponsive" bearing, so if you ever decide to get into the more advanced tricks you'll be covered.
