The Phantom 4 is out. I've got one and it's pretty awesome, but in reality, it's not THAT much better than the Phantom 3. If you're looking to buy your first drone I would suggest starting with something more affordable anyway. Right now you can get a new Phantom 3 Advanced for just $599.
The Phantom 3 came in three models; standard, advanced, and pro. The advanced has all of the same features as the pro but it can only shoot 1080 and not 4K. 4K is certainly better, even if you plan to export in 1080, but it isn't 4 times better. The low bit rate of the Phantom 3 Pro limits the 4K resolution quite a bit. That being said, if 4K isn't a must for you, this deal may be right up your alley.
The seller is cookieelectronics and they have over 5800 positive reviews with a 98.6% positive rating. This is a legit seller and if the drone comes to you broken they will give you your money back or send you a new one free of charge.
