My brother in law owns the first generation DJI Phantom model. I think more and more people will be incorporating these into their vacations and how they document their trips. Just think of how few people owned cameras and camcorders not that many years ago and now you can film, edit and send pictures/video to people right on your phone!
My brother in law will be taking his on his adventures and making some of the most amazing home videos no doubt. Here are a couple of videos others have posted showcasing some of the things you can do with them. One guy took his into the everglades in Florida while they took a tour with airboats. He controlled it right from one of the airboats. The other video is of the aerial lift bridge in Duluth MN.
As for price go on Amazon and look up DJI Phantom. You can score the first generation for under $500 and the latest release for under $900. You can attach a Go Pro Camera for $200 - $300 or the new DJI Phantom II can be bundled with a camera that is just as good as the Go Pro.
