For learning how to fly in the sub $100 price range, get a Hubsan X4 H107C - don't be put off by the low price - they are crazy fun to fly. For the $1000+ price range, the DJI Phantoms are great. For the $500 price range, check out http://www.thepocketdrone.com - the most successful drone Kickstarter campaign of all time (raised almost one million dollars). Disclosure: I work for AirDroids who manufacture the Pocket Drone.
