I bought one this summer specifically to film slalom, it's an Autel X Star Premium, $650 refurbished directly from Autel (looked brand new), or at Best Buy new for $800. www.autelrobotics.com. It is easy to fly, as any of them are. I did a lot of research before buying, it is the highest rated in it's class, better than the comparable DJI drones in that price range. Customer service from Autel is excellent, and the drone is very, very smart with a lot of built in safety features. Their site has a lot of how-to videos so I basically knew how to fly it before I even received it. Comes with a very nice hard case too. I am the guy mentioned by @LeonL above. As Leon mentioned, the drawback is the max speed of 32 mph and if there's any wind, it wont reach that speed. It does have an excellent high def video/still camera and takes great video. If you want one that will keep up with a 36 mph skier, you will need one rated for at least 40 mph. @rwskier mentioned the DJI Mavic Pro that goes 40 mph in sport mode, problem is all the safety functions are disabled in sport mode and believe me you want the safety functions or you will end up with your drone at the bottom of the lake. If you want one that goes 40 and keeps the safety functions, you will likely spend at least $1200, probably more. No matter which drone you buy, the max battery life is 20-25 mins, so you will need a minimum of 2 batteries, I have 3. Extra batteries are $80-$100 each. If anyone wants to see video I took, PM me and I'll send you a link to my dropbox, it's very cool.
