If you live and fly in or near complex C or B airspace, or 30 mile Veil C airspace of larger commercial airports, the ADS-B In option would probably be a wise investment in yours and all other pilots safe airspace and well being.
I state this because I got to see first hand, the benefits of it flying around here East of LAX last Saturday. PIC would have gone crazy looking at a sectional map trying to figure out exactly where we were to meet all the airspace requirements.
