The Phantom 3 is very easy to fly, never tried the Mavic Pro.
Don't know if this suits you, I have no affiliation whatsoever with these Chinese crowd, but I'm told they are very reliable, and hope they are, as mine is on its way.
They will pay VAT and Duty so there are no hidden charges when it arrives.

The difference between this and the Phantom 3 Standard?
- 4K Camera
- Improved 720p, 30 fps Wi-Fi live view
- 4000m (4km) (12000 ft) RC Range
- Vision Positioning System
If you register with topcashback.co.uk you also get about £29 back so you pretty much get a Phantom 3 Pro (or close) for about £380
Again don't shoot the messenger, but the price is very good.
