There inspire is a great machine, but like i said, to get great video from it you need the X5R. If you're not prepared to buy the X5R then you have to accept its video limitations. I have seen x5r units going for good money too.
The phantom 4 advanced is an AMAZING bargain. I have seen them second hand for well under 1000.
You won't get anything that beats that in terms of quality and performance, cost.
The mavic air is also a bargain, the smaller sensor is not that bad an issue if you mostly shoot in good light.
The 12mp photos are the only thing which puts me off. This isn't 2013.
But like I said, wait until the mavic 2 is announced on the 23rd, that will probably lower the price further of existing DJI products, or you might find you want that if they do something great with it.
