The Campark V30 is one of the better sub $100 action cams, featuring native 4K at 30FPS with solid electronic image stabilization. This camera is easy to use, decently built and has acceptable audio quality. Of course, stepping up to a more expensive camera will net more customizable video and better build quality, but the next step up is nearly double the price and for most people and those just starting out, something like this camera will be more worthwhile.
