I need to get Dual Shock 4 [DS$] for playing some games on Rpcs3 that needs the gyro function of the controller.
I'm also interested to map mouse to the gyro controls of DS4 to see if it works well like Nintendo switch's gyro aiming.

I know Sony showrooms might sell DS4 but if there are other stores that sells legit DS4s at cheaper price, I'd like to buy from there. I need to get a bluetooth adapter too.

What would be the price of a real DS4 here?
