Here's a mini basketball set for use indoors. It looks like it might be from the same manufacturer as the bat & ball set seen above, as it too has stars and primary colors as a theme. The backboard has the winged ring (reminicent of early Sonic games) but with SA1 style Sonic in it. The ball is rather creativly designed as well, in more primaries but this time with dots instead of stars. It looks like it has everything you need included, even to mount it. These were available at TJ Maxx Stores in the USA. However, TJ Maxx is a close-out store, for the most part. They were likely available elsewhere as well.
