The DJI Phantom 3 Advanced is my top pick for cheap commercial drones for sale. It comes with a built-in camera that can shoot 2.7K videos and 12 megapixel photographs. What I love most is the live first person view streaming direct to my controller while the drone flies for up to 23 minutes at a time.
An extra battery is recommended if you want to increase more flying time during your sessions. You can also get a pair of extra propellers, 64GB memory card, remote control strap and a carrying backpack.
If you want to upgrade, you can try the Phantom 4K, which captures 4K videos with a 25-minute flight time. The maximum control distance is limited to 1,200 meters, which is not bad considering the alternatives.
And if you want to go to the next level, the Phantom 3 Professional is what you need. It captures 4K video, offers 23-minute flying times, and a remarkable 5-kilometer control distance. And best of all, it comes with obstacle avoidance capability.
