I know a few forum members are into radio controlled devices. Have any of you spent much time with the RC drones that have attached cameras? I've seen some videos made by these drones, and the unique vantage points from which you can approach a scene really opens up interesting possibilities!

For those who have messed with them: What's a good brand/model? ("good" as in most bang for the buck, not as in most expensive) and what would something like that cost? Preliminary web searches turned up lots of hits under $100, and that isn't what I expected. Could that be the true?
