is there such a thing as a DVI switch??

ya know, to hook up 2 pcs to one monitor?

i know theres a vga solution but both my pcs have dual dvi cards and all ive been able to find is one that takes 2 dvi signals and switches them- but only to an HDMI out.... i have no use for that

if someone knows a good place to start looking, please feel free to toss me some links.
