The HORI Battle Pad (Zelda) GameCube Style controller for Nintendo Switch will release December 7, for $25: https://www.amazon.com/Nintendo-Switch-Battle-Zelda-GameCube-Controller/

I’m surprised that this Nintendo Switch controller is so cheap considering the extra functions it has over ordinary game controllers, like that anti-snapback Tech, Turbo settings, option of swapping the L/R & ZR/ZL functions, etc.

And the HORI Battle Pad (Zelda) GameCube Style Controller For Nintendo Switch kind of looks pretty cool too, with faster ergonomics and better grip texture for the palm and fingers.
