I've always admired GoPro cameras for the quality video they record despite their small size. Right now on eBay the official GoPro store is selling a refurbished Hero Session camera for only $119.99 with free shipping. This camera is waterproof up to 33 feet without an additional housing and records 1440p in 30 fps or 1080p at 60fps. It features a simple 1 button control and connects via wifi or bluetooth to your phone to manage settings and view footage.
