I bought a KLN-90 a few years ago and did my IFR training with it. Now have a 430W. It was a good unit and King is still selling DB's at a reasonable price (same as Garmin, I recall). Back then, decent units were going for $800, probably less now. It uses ARINC also. I believe it also had the connections for the old school CDI's as well.
