I know .

.his nikon camera lens was $500 as well , my mate that filmed this lost it in the sea too ,ET never came home ,he now has a phantom ,which is around 2000,
he said it does the job ,and is ok in 20 knots ,he did say the camera can not film or turn completely around like the inspire ,so it is flown a different way ,I have never flown one ,but i have 3 friends who have them (phantom) ,and all have great footage ...thats why i don't need one ..LOL.
as someone said earlier ,you may crash it ,so don't throw to much $ one ya first one .
