Well, if you do go for it then you probably won't work on your console pong project. And if that happens, I won't have another console pong machine to compare the one I'm building to. I'm building mine like the red pong bartop, but haven't had luck finding the coin acceptor. It is a christmas present so it will have to be finished by then.
So lets say you buy this paddle ball. What will you do with the Cherry Master? What will you do with the pong console you bought? Your budget for a pong game has jumped from $50 to $100. So maybe you shouldn't buy.
But then again it would be cool to have and probably wouldn't be hard to fix. (really I have no clue) So on that note you should buy.
Anyways.. I haven't given you an answer so good luck.
