Before everyone starts saying "Monoprice", that was the first place I looked and I was shocked to see that they didn't have any of these. They only cary the triple RCA stereo/video ones for some reason. Looking for just a regular video-only composite cable (yellow only...no red/white stereo included). Just did a quick check of Amazon and this was the cheapest one I could find ($16.27):
