With the upcoming release of Smash Bros. Wii U the well beloved Gamecube controller will go into production again which will be compatible with the game ( your old gamecube controller will work also of course ) so no need to buy less than good third party controllers. Along with the Gamecube controllers a controller adapter to attach 4 of them to your wii u will be offered. Nintendo stated this will work only with Smash Bross Wii u ( for now ).
