Actioncam Upgrade

I have a couple of GoPros that I've taken on a few trips. The problem that I've always had with them was the lack of image stabilization. The shaky footage can be somewhat solved with post-processing, but it's never perfect.I think I've decided to trade in the Hero 4 Black for something from Sony -- as soon as it's released. It comes with image stabilization as well as a bigger battery. The native GPS and bigger battery are also plusses -- as is the native waterproofness of the unit as well.I think it's time for another Craig's List sale for these as well.Anyone in the market for some GoPros along with accessories?
