Flightline FL-760A Com Radio: $575
As close to "brand new" as you can get, with 10.5 months of manufacturer 1 yr warranty remaining. I installed it in my plane and flew with it less than 5 hrs. before removing it. Reason: in the airspace I fly through I really miss the ability to monitor the standby frequency, a feature not included in a radio at this price point.
Works perfectly. I'm including new connector and pins, and the original receipt with serial # for warranty coverage. I'll also include CONUS USPS priority shipping.
