Well, more than likely I'm going to put my P3 Pro with all the accessories to sell on Ebay, then get a Mavic from Best Buy 12 month financing later. In the meantime, I'll use my P3 standard. Question is, how much can I expect to get for a p3 Pro that is 3 months old with 4 ND filters, extra battery, 3D printed gimbal saver, windsurfer, a couple of other 3d printed accessories for the remote, as well as an original DJI case?
