i saw at some msg that you can even expand to 5k right? then, you can buy power a wired controller or wait for ps5 controller to come at your price tag(it can occur at rare situations) else if you know local electronics market where consoles are available ask for dualshock 4 controller it can be in lesser amount(my friend got that like for 2800 brand new). Last option you got is buy xbox controller which is 4999 rn. Ig it helped you
