I'm at the point in my build where my cabinet and control panel are nearly completed and I need to look into extras

. The computer I built is pretty decent and capable of running the newest games like SF4, Dirt2, Batman, ect. For some of these games the stock control panel just wont do, specifically games like Batman, or any FPS style game where movement and aiming require 2 directional pads.
My question is what types of game pads is everyone using? I was thinking I like the Xbox 360 controllers and you can purchase the wireless usb dongle and control off amazon for around $50. A big plus is they come in Black which matches my cabinet. Everything is accessible on my cabinet from where the player sits normally. I don't want to have to get up to get a controller when I start a game. Call me lazy I Guess.
Do they make a 360 gamepad holster? If not, Do they make them for any game pad for the pc?
