How is you search going? I was in your same boat a few months ago, went to eBay and had to pay just like everybody's has mentioned before. But I came away with one extra and let me know if you still interested, I'm not going to take a beating on this one but I won't gouge you either and the price is 700.00. They said it was brand new and it still has the factory wrapping on it but take that with a grain of salt. I will shoot a short video show it linking to my P4P V2.0 if you want but other that I can not guaranteed anything. The reason I have two is because the first one off eBay did not work and had to send it to DJI for repair and had to pay two hundred bucks for that, but it works now. So if you still have a need and you think it's for you let know.
