I haven't played Centaur, so it might well be the case that it is as much superior to SW as the above posts indicate. Still, I think it is worth putting in a favorable word for SW. It looks and sounds good, is easy to understand, and, not coincidentally, it is always one of the most used and appreciated pins when we have parties. Is it up there with our very best pins? No, but they also cost considerably more. For the money, it's quite a good machine, especially in a large collection, and especially as an approachable pin for guests.
