Hitaway Tennis Training System. Who needs a tennis court when you can play just as well in your garage or rec room or backyard driveway. This baby lets you hit away, get out all your frustrations, when it's cold out, rainy or you're just too darn lazy to drive the 2 minutes to the local tennis courts.

It's cheap, it's light and foldable (take it anywhere -- to the beach, a picnic, even your next "too long" neighbors' dinner party). It's a breeze to use, and it might actually help your tennis game.
