Well 2 of the guys in the office have bought some "Nano Quads". Their price point was around the $35 mark and I was interested initially, but sceptical.
They bought the bright orange Skeye Nano Drone. After 3 or 4 weeks they arrived. Oh boy are they tiny or what!?! Easilly small enough to fly inside they were both buzzing around the office, and with a charge time of what seemed like 10 minutes my interest was increasing. A simple plug into the USB port on the PC and they're up again in no time. Flight time was about 5 minutes I think.
