Depends on which drone you already own. If you have a P4P and your are focussing on video whithout minding the extra weight & noise, I would cancel.
If your focus is on still photography you have a great item with the M2P. Image quality compared with the P4P is hardly noticeable and doesn't justify the bulky Phantom.
There is one thing in general abot the M2P:
It is SO MUCH quiter and smaller then the Phantoms and your 'footprint' is way lower!
With the MP2 I fly somewehere where I wouldn't take a Phantom
I predominantly use my drones for video, not stills. I have an MPP now. Was planning to sell it after getting acclimated with the M2P. This was ASSUMING the video was going to be as good or very close to that of the P4P. I'll not likely ever buy another Phantom as I've owned 2 and experienced stress cracks with both.
