Local classifieds sites (Kijiji etc) are great, but provide no way of searching for a specific drone or series of drones. For example, there is no way to search for "Phantom 3 series drones" specifically, and no way to target only specific manufacturers you are interested in purchasing from. With the growing (or should we say exploding) drone market, it is very important to have a great venue to list your used machines and to search for specific drone services, all in one spot.
