What are some good entry level remote control helicopter toys for adults?

My boyfriend (mid 20's) has been wanting one for a while. I wanted to get him one that he could learn without spending hours trying to figure out, and might entertain him longer than a day. My price range is around 50 dollars or so, but please recomend anything you liked - I would be happy to hear about it!

Thanks!

airhogs usually quite cheap but very fun but becareful of the ceiling
