What drone do you use?

[Simon Daniels]

I've seen drones mentioned on here a few times in the context of looking at roofs pre purchase. I am looking into buying one to get eyes on rowhome roofs without dragging an extension ladder with me every time I look at a property. 

Any recommendations for brand/model? Looking for something at a low price point since I'll only be using a for a few minutes at a time, but something with sufficient image quality to get a good sense of a roof's condition.
