I am fairly involved with Drones and the advice from Piros is spot on regarding quads. I have my commercial drone license and am also a team pilot for www.multiwicopter.com and my advice would be this.
1) Go and buy a cheap $100 mode 2 toy to learn orientation and control. Better to crash that than a more expensive setup.
2) If you get a more expensive Drone make sure you know how to fly it properly (not relying on GPS) and also the laws involved in what you can and can't do. CASA 101 are the regs.
3) Drones go wrong so never put your drone into a position that it can damage people or property. When they go wrong they drop.
4) NEVER EVER fly over people, populated areas or above 400ft (AGL). Legally you need to keep 30m away from people, property etc
5) Always ask permission if you are going to film someone
The Phantom is a great product in the right hands and for the money is hard to beat. You just need to make sure you fully understand it.
I will also warn you now that as a hobby it is more addictive and expensive than you first think.
