I suppose you could get something like this:
I just did a quick search on 'VGA Splitter' and that was like one of the first things I clicked on, so do more research and you might be able to find something like that for cheap. but hey $60 really isn't too bad either, and I think that thing will allow you to display up to like 4 monitors at once. It might not be at all what you're looking for though. Sorry if its not, my minds somewhere else right now =P
EDIT: Forgot to mention, with that splitter you can use your normal VGA connectors instead of having to insure you got one normal vga connected monitor and one digital or one s-video and like they said, s-video is for displaying on your TV so I doubt you'd want that and also like they said most of the newer cards come with an adapter to plug a VGA monitor into the DVI connection.
