I have All Star Stats and they are great! A bit pricey, ($149) They claim they can tackle any scoring system, and they back that up! They accomodate our older range scoring system plus a lot of bonuses we have too. My only complaint was that their live scoring was slow, but it's only week 1, so you have to cut them some slack. I highly recommend them.
