It depends what you want to do with it. If you just want to cruise around and take photos, then yes - go for RTF (ready to fly) models; such as Phantom and Mavic. However if you want to learn how to build one, I would suggest taking mini-quadcopter route - in the process you're gonna learn alot, this huge guide covers the whole process: http://dronenodes.com/how-to-build-a-drone/. When you build LOS (line of sight model) you can add additional equipment for FPV flying, and that's where the real fun starts! :)
