DIY VGA splitter????

Hi guys,

I finally picked up a used(barely.. mabye 20 times tops) OHP, and I'm trying to get it set up with my panel in somewhat of a permanent fashion.

I plan on constructing a 15' or so VGA cable to run from my HTPC to my projector. My question is: can I make a simple splitter using some vga plugs so that I can use the PJ and monitor at the same time? Or will that degrade the signal? I don't want to have to unplug/replug things every time I want to use it.

Thanks!
