I've had my P3S for about 3 months now, and I am completely satisfied. Then only thing I missed (that matters to me now) is range, and the Itelite DBS01 mod took care of that, for about $90. The video is fantastic, and flight time is a bit more than the others, probably due to the absence of the ground-radar module. If I lost it today, I might consider the P3A, but I would probably buy the Standard again. As far as GPS goes, I don't miss the GLONASS, my Standard has never lost GPS. Also, keep in mind, the camera on the Standard was 2.7k as released. At that time, it was superior to he P3A @1080. Now the P3A is 2.7 thanks to SW updates. I researched the HELL out of this purchase, knew what I was and was not getting, and bought the Standard. It's been nothing but great for me.
