1st check in. New guy with part 107. Weeks ago saw phantom for sale at pawn shop. Bought it ( 3 standard) pretty good deal but only has 2.7K camera. As I found it is useless in a commercial environment. Everyone wants 4K. Also saw a phantom se which has 4K camera, but seems to be a beginner or hobby version? Would the se be worth it in a commercial environment? Or should I go to the phantom 4?. Thanks in advanced for your help!
