Which Razer Keyboard

Hi, I am looking to buy my son a Razer gaming keyboard and mouse for his birthday but have no idea which one to get. Any help appreciated please. He wants to be able to use with a PS4 for Fortnite and other games would like usb or wireless but don’t want to pay over £150. He likes to play on his bed and at a desk / table and we have a laptop which has windows 10 which we will set it up on. Hope you can help! lisa
