Inexpensive scuf controller for Xbox one?

I would like to buy a scuf controller for my Xbox one (CoD mw) but I can only find those that cost about as much as my complete Xbox… Is that cheaper than almost 200 euro? I just need the two buttons on the back. Or can you somehow adjust the button assignment of the controller as you want (not the default settings in the game)?

Xbox wolverine costs 90 euro has 2 buttons on the back
