I'll add another vote for the V911. The 4 channel is much more fun than the 3.5 channels. And you can fly it outdoors.
Honestly, I wouldn't even waste your time with an s107. Its worth about 10 mintues of fun before you put it away for good. Slow, unresponsive, and limited mobility. Not even good as a "learning" copter to move to a more advanced model because the controls on a 3.5 channel are completely different than they are on a 4... you will have to go through the whole learning process anyway.
When what to my wondering eyes should appear, but a bucket of wings and a six pack of beer!
