VGA 'Switch'er?

I use one monitor for both my PC and xbox. It's a regular PC monitor.
Unscrewing the damn thing is a pain, and I'm wondering if there's anything that I can plug both the cable from the PC and the cable from the 360 into, and then that into the PC to make transitioning as easy as a flip of a switch, or press of a button.

Does your monitor happen to have a VGA -and- a DVI connector by any chance? Because then you can just switch from video source on your monitor (VGA/DVI) without switching between cables.

My xbox360 is on VGA and my PC is on DVI btw.
