Thanks for the reply! Yes I know I should have probably read more, its just that I spent my whole day at work drooling at control panels, when I was done I had so many questions!
I will check out the U360, I am not really going for authenticity, I just want to be able to play it correctly and not have a cluttered panel.
I defiantly want a 4P control panel. We entertain a lot at my place, almost weekly, and we can't get enough of 4 player games. (Rock band, rock band, rock band!). There are some non mame 4 player games I'd like to play too. Atomic Bomberman, You Don't Know Jack Series (3 player), Powerstone for Dreamcast, Mario Kart, Golden Eye, Hungry Hungry Hip... wait nevermind.
I might double up the start buttons as insert coin buttons.
Thanks for the tips!
