My scoprio controller felt like it was put together poorly so I ended up buying one of those blue tech style controllers with the rubberized backing. It feels a lot better to use than the scorpio controller but it also has some issues with the shoulder buttons. The 360 controller was put together so well, I don't get why this controller they bragged about spending over $100 million developing seems to be so poorly constructed.
I would love to buy a 3rd party controller but all the wireless ones are done via stupidly expensive controllers...like Razr and Scuf.
Honestly, I'd rather they enable wired 360 controllers to work on X1.
