A complete review of the cheapest drone that can carry a GoPro, or other action cameras with ease: The Tarantula X6 (http://amzn.to/2ihJbkZ)
Pros: Great power, great range, amazingly cheap price (roughly $50!), and plenty of spare parts available. Spare batteries are cheap (~$8) and the drone can carry any of my action cameras. Combine it with good conditions (low wind) and a good action camera with electronic image stabilization ( such as the GitUp2 or ELE Explorer Pro) and you can have fairly stable, impressive footage for a fraction of the price of a Phantom. Can even carry a FPV transmitter and allow you to fly first person view-style!
Cons: For the price–nothing! Just make sure to stock on spare parts because it is a brushed drone, and the gears will wear overtime (replacement parts less than $10)
