Firstly, have you used the "search" function? I know that's reall fatuous question but this topic has been pretty well covered.
Are you talking about the Happs PacMan/Galaga 4 way stick? If so then yes it is an awesome 4 way ( the best IMHO ) but if you buy it as is you won't be able to mount it in MDF as it is metal control panel only. You will need to either bmake a mounting plate or buy one. Oscar is your man for that.
