There's a bunch of these that all look very similar. Claims to have 24p and a Panasonic 34110 sensor. Anyone ever see one in real life? $100.

Another one with Sony sensor. Uses a 4:3 squeeze.

Wasted a lot of time myself with modded cameras and various aftermarket lenses for 1/2.3" sized cameras which may or may not be relevant to the conversation. This includes, Yi4k with RIBCAGE and various Gitup cameras. Including trying to solve exposure headaches with ND filters etc.
THose cameras (the action cams I mean) are good for one thing, timelapse. Or perhaps for drones? And not even that great for timelapse. I didn't have too much trouble getting a sharp image with some of the lenses available but getting usable video was another story. Usability and dynamic range are what matters to me. I wouldn't even bother with one as a b or c cam now..
