On the subject of bouncing, I found a cheap alternative that makes great balls to practice with at a fraction of the price. 12 Icy Bouncy Balls for under 15 bucks!

Compared to Oddballs bouncing balls they're a little smaller, (60mm instead of 68), but they've got at least 90% of the bounce of the pro balls. Just the thing if you want to learn bouncing and don't want to shell out bucks on equipment. Plenty of spares to lose or share, too.
