switchbox/controller help

hi. im trying to find a switchboc/controller that i have seen before but i can not find it anymore. it is a xbox controller. ive found like a playstation controller but thats not really what i wanted. so if anyone knows where i can find a xbox controller to buy online, or if you know how to build one. can you help me out. thanks

If I remember correctly I seen those in an ad for Autoloc, its been awhile tho since I seen it.
