How can I hook up multiple monitors to my laptop?

I have a laptop and I recently discovered desktop dualview. I want to use my laptop as a dvr on my tv. I know I can hook it up and it will work great for video. What I want to know now is how can I hook up piles of monitors with VGA connections? I have seen VGA splitters but they just duplicate the same display. You can buy old monitors at the thrift store for less than $10 a piece. Does anyone know of a product that could hook up to the pc card slot or USB 2 and facilitate this?
