I'm after PS2 instead of USB because I want to be able to use it with my KVM extender, which doesn't have USB. I'd like the mouse to be wireless, but the keyboard doesn't have to be. I already have a Gyration wireless RF for living room, so it doesn't need to be RF. The less battery replacement the better. It'd be nice if they're good for games as well as standard work. I'm thinking MS, Lgitech, Saitek, £20 - £30. Any suggestions appreciated. Thanks.
