I've been flying for 12 years and have used Futaba and Airtronics. Not a single problem with either one. I have the RD 6000 and I really like it. Don't be afraid of the Airtronics. It just dawned on me that in 1992 I bought a Air Vanguard and Futaba Conquest radio and paid 250.00 for each. Today, you can but a basic computer radio for the same money. Think about that.
