I just joined the masses and bought one on eBay for $80 to see what all the fuzz is about. Has a camera and gives amazing footage streamed back to the iPhone. Best $80 I ever spent! Almost identical to fly to an electric or nitro model Heli. As an electric model it's great fun, highly maneuverable and a real blast skimming along a foot or two off the ground up to a couple of hundred feet. When it all goes bad just cut the throttle and she drops to the ground safely. It's not heavy enough to damage itself when it hits the ground.
I can see why everyone is getting into it now...
