Hey if you have 3k USD to dish out...then obviously Inspire2. One thing I like about it is the duel camera, but anyone can do a similar feature on a p3 or a p4 via LItchi. They just have to do a zipline and then they can rotate the camera 360 while flying one direction.
I think I want the Pro. I was getting ready to pull the trigger on the 4 and a new iPad but I think I am going to go this route. Need to save a little more and I will be there. I really need to do some thinking now. This purchase decision is going to be harder than I thought.
