These handles are crazy fun. Since the new GoPro HD Hero2 supports HDMI output, it's possible to create a top handle for a low flying GoPro with an external monitor. A setup that skateboarders love to shoot with.
GH2 - DIY Top Handle
I just posted the availability of these new P&C Pistol Grip handles late last night and we didn't expect such a response. The P&C website has been updated to 'out of stock' status. Until we get more stock, you could still grab one with a small amount of remaining inventory available at eBay and Amazon (below).
