KVM switch

I just bought a new TV that has a computer display connection. I want to know what is one of the best KVM switch i could buy to hook up my computer monitor and the TV so I can switch between them both. I have crossfire hookup right now but i want to make to so they are both hooked up on one video card on one dvi port.

i forgot on the 4850 i can use component cables to hook the video card to the TV and would probably look a lot better and cheaper then a KVM switch.
