For what it's worth I've just bought the latest Sony action cam after comparing all the different options out there.

In my opinion the Sony produced the same, if not better quality images and comes with a wrist mounted LCD monitor for the same price as the GoPro without the optional "backpack". As far as mounting options, the camera includes both helmet and flat surface mounts. You can also screw a little RAM mount ball into the base of the camera and the options for RAM mounts are endless.
