cheap XBOX controller

So people, my controllers' LB button broke. Yes i know you can repair it sometimes, mine however totally broke off. I raged on bf3 and hit it against the wall lolz. So here i'm asking for some cheap ways to get a new xbox controller. Stuff that could work in europe since most of the best i found is US only. By cheap i mean less than 20 euro.

Gamestop makes their own controllers, i find them to feel cheap, but they are generally are cheaper than the regular ones.
