If you could buy a 120mm cannon, or a torpedo, or an ICBM for a couple thousand dollars, would you want that too? You don\'t need it, and it doesn\'t serve any purpose. It reminds me of that scene in "Rollerball" where the party guests went outside to burn down trees with a flame pistol for the hell of it. I think you should save your money and do somthing constructive with it instead of blowing the doors off cars.
