Ok I'm new to this ,so what am I looking for in first proper drone ? ive traweled the wonder web and youtube channel and decided that dgi is yhe way to go.Ive looked at the phantom and have become really impressed with the overall comments and reviews.How do I decide between each model what a dilemma .At the moment there doesn't appear to be much difference in price between each model and if you go secondhand you can get even more for your money aslong as you know what you are looking for.I have looked at each model in turn looked at my budget and thought is there anyone out there who can throw some advice my way.i looked at the standard and was told that although good value for money it was a lower spec than the pro and adv and the build quality was lower also ,but then you are paying less.The difference between the pro and the adv was purely the quality of the image viewed and the difference in the chargers.Do I really need the higher quality image of the pro do I need 4K. I really like the P4 the latest model full of the latest Tech but I read there have been issues with bugs etc have these been resolved ?I don't like the sound of my investment falling out of the sky into the nearest body of water I know all new tech has minor ailments when brought to the market but have these been resolved with the P4? Ireally am trying to convince my self to go out and buy the P4 but the P3 have had such good press along with the fact you can upgrade with the Liche app .So if there is any one out there who can steer me in the right direction I would very much appreciate it also I have noticed that there is a lot of P4 drones being sold secondhand which are barely out of the box over the internet Is this a sign I don't know thankyou again for any advice .
