It really depends on what your hubby would want to do with it but... honestly getting him a drone in the price range you're looking at might not be worth it. Taking a motorcycle as an example... If your hubby wants one and he's thinking "Harley Davidson", you're looking at mopads. LOL On the other hand, maybe your husband does want a mopad? o_O Any way to ask him or find out from friends what he's looking to do with?
As for its uses... I've seen some ppl use drones to take incredible scenery. One of the best I've seen was for fireworks! But I'm sure you'd have to be an expert in flying one to do this...
