Official NBA basketball hoop?

You can find them in sport stores, look around. By the way official set up in the NBA is the hoop 10 feet off the ground and a diameter of 18 inches. The backboard is actually 6 feet wide and 3.5 feet high in the NBA but I haven't seen a backboard that big in a store yet. The expensive ones have the new spring loaded rims so you can dunk on them without them breaking after a while.
