Depends on how much you want to pay and what your application is going to be. If you have to have the best and thing your going to put some serious power to it (something over 500) I would suggest looking into a dart block. Those are the strongest and best out there, they cost serious cash though, around $2200 or something around there, but it will probly be the last block you ever have to buy.
