Mark I have a A-200 that I got for my project.I got thru Wicks and done a lot of research on them.They are nice radios,but I was told by everyone I talk to not to waist money on the higher priced one for certified aircraft.They are the same radio.Everyone I talked with said they work great.Brian Kraut would be the one to talk to he deals with them all the time at work and is building me a harness for mine.He should be able to answer all your questions about the radio.
