Xbox 360 Controller Swap ?

Hey guys I am currently looking for a controller swap if anyone is interested. I currently have a Gears of War 3 Limited Edition one and I am currently looking for a Modern Warfare 3 one in good condition. Ideally I am looking for a Modern Warfare 3 one but I would also like any offers for any other rarer controllers like the Resident Evil or a Halo one. If you would like to trade get back to me.
