I guess it's all dependant on what you are willing to spend.  I've been looking at systems from $29 to $5000 or better, with auto takeoff and landing. These systems can can be programmed to do specific tasks at preset times or locations. Like take pictures, turn on a vidio camera, drop a marker bouy.and more. I my self am working on a uav for search and rescue capabilitys. using a true anphibian platform.</p>
