I've flown the Parrot Drone and its a lot of fun, you can buy a fast charger and a couple of spare batteries and literally fly all day. Be careful in the wind, it's light and underpowered, you could lose it easily. You can also modify it to fly with a real radio instead of wifi if you want, its not too complicated to do.
Plenty of info on the stuff you can do to the things.

My new camera ship Zombie 2 is under construction. Will be shooting 1080p video and a range of 1 to 3 miles depending on terrain. Costs a lot more and has to be built and customized, but thats the kind of stuff I like doing.
Sketchup image, and the actual chassis with a couple of changes:
