I also had the x-arcade sticks (an e-bay mistake) - they are made of doo doo. I purchased the Happs p360's and they are excellent for the fighting games. They have no microswitches, therefore the throw is constant all the way around. These feel like arcade joysticks, especially for the fighting games.
Since this is your primary interface with the computer, I am of the opinion that these should be the top of the line, and they only cost a few bucks more than the Happs Supers. They also have the same mounting holes as the x-arcade sticks, so no extra work was needed to mount them. You will need a 5v power source from your 'puter (IPAC, USB wire hack, or direct from CP).
