Haha, I got them from Casey's Wood Products, Inc., through their website. They were the best deal I could find (factoring in shipping cost as well). It is the 3/4 hardwood wood ball. Model #179. I ordered 250 (and used nearly all of them) and got them at $0.058 each plus $8.95 shipping. To my amusement, they came in a lot smaller box than I'd envisioned.
