I have a Henry Viper yo-yo. Its one of the cheapest yo-yos out there that has a ball-bearing axle... cost me about 40 bucks.
If you want to go real expensive... check out the Silver bullet II w/tortoise finishing... that i'll run you about 100 bucks.
Before you start thinking i'm a freak, I just want to say that Juggling is a big hobby of mine, and yo-yos is just one of those things you pick up if your into it. Any big juggling convention will have world class yoyoists to learn from. I even saw the yoyo world championship at the international juggling convention in pittburgh a few years back. Insane!
