Gamepad for archviz?

Hi friends, I would like to run my demos using a gamepad. I saw the dualshock 4 but it is expensive. I don’t need to jump or fight, only need to walk and watch. Did you try any other cheaper gamepad I can use with Unreal?

Thank you.

most generic xbox/playstation controllers work in ue4. eg i have a 360 afterglow controller that i picked up for $15 that works fine.
