I have the possibility to buy a P4 standard used for US1300 or a P4 pro v 2.0 for US2000 which is also used too, but it is sell by the dji representative with warranty. I just want the drone for fun and to make some videos. I am affraid to crash my P4 standard since this drone does not have all the security crash sensors and since I am new, . Which one would you choose? By the way, here in my country it is not easy to get a P4 pro V2, and a new one costs around 3500.
