How much will i sell my xbox for?

I'm selling my xbox 360 this comes with a 360gb hard drive (which cost 100 euro) plus 6gb internal memory 9 games (fable 2, minecraft, alone in the dark, CoD black ops assassins creed 3, final fantasy 14 skyrim legendary edition, GTA 4, CoD MW3) and 2 wireless controllers this is in great condition except that on one of the controllers RB is a bit faulty i was thinking along the lines of somewhere between 150 to about 200 euro but i'm unsure

Around $225-$275. This is translating it into US dollars, I don't know how to calculate the exchange rate and whatnot. But if you do, then this should be a good guideline. Your controller with the trigger issue basically makes it worthless as it sounds like more of a headache than most will put up with.
