I have always been put off by the ridiculous prices of HDMI/DVI KVM switches. What kind of circuitry could they possibly contain that costs that much?
I believe they are just pushing the prices as high as the can get away with. They just need to keep the cost at less than buying 2/3/4 monitors (which is a very high upper bound), in order to make the deal look sweet. I would very much like to be proven wrong, but at least in my eyes it looks like a scam.
Unless space is a severely limiting factor, I would rather spend that money on buying separate screens/mice/keyboards.
Looks like switching isn't too expensive to me: http://www.amazon.co.uk/Duronic-Switch-input-output-Switcher/dp/B0020426AG/r... http://www.lindy.co.uk/usb-switch-4-port-usb-2-autoswitch/42784.html
Yes, it is two buttons to press instead of one, but having a real USB switcher instead of a KVM solution where you can only switch a mouse and keyboard (the set up I have) sounds great to me.
