Recommendations for Action Cam/GoPro Under $200 for Geprc Vapor X5?

If you want stabilization then the new GoPro hero is really good and light weight (when I had one it did not allow turning off the stab). If you don’t want auto stabilized then I’d look on the used market for an older model. 4k anything GoPro and the footage will be very good. And you can stabilize in post if you want to. Runcam had a light 4k option for a while that was pretty good too. Might see about that as well. There are lower cost choices, just have to check a few out. Keep rippin. 

Runcam Thumb Pro 4k

I love my DJI action 2, the picture quality is phenomenal while its also light and sturdy. Im able to find them second hand on facebook marketplace for $200 AUD or less fairly frequently so im sure you'd be able to find a second hand one for < 200 USD/Euros easily too
