I am looking into buying an indoor(and possibly outdoor but i will probably be using it indoors the most but i dont know if they have one for both indoor and outdoor) helicopter. One with good battery life and easy to control. This is my first helicopter to buy but i have flown some before at friends houses and really enjoyed it. I am looking at helicopters in a price range of no more than $50.

Here are some i have been looking at:
