I use a GoPro Black HERO 3+ (I think the new ones are GoPro 12's). I bought it off e-bay and it came with a ton of extras, all for under $100. It has sound and I tape the microphone to the lower part of the trunk, to avoid wind noise. I cover the mic with a "dead cat" (not a real one) to suppress the wind noise further. Made the stand out of Harbor Freight suction cups and pvc piping.
