A good controller for Alien ware 17 R 5

Hello, I was looking for a suggestion. I have an At play Xbox 360 wired controller that has a right analog stick drift downward and was looking to replace it. I am hoping that I can find a new controller (Wireless preferably). I have tried searching which one would be a good suggestion but have come up with nothing. I was looking for something affordable within $ 100 range.
