Never in the world!
You can do a quad that is flying better, but you can never get better pictures/videos from a DIY-copter. Also no sonar, no optical flow, no digital video downlink with a DIY-build for that money. You need only to buy a P3, and if you already own a smartphone you can do FPV (charger, ...) everything (even the SD-card is included).
