I just got back into serious flying withing the last 6 months. To do so- joined a club. Well, actually call it re-joined. Had been out of flying for some 8 years- probably more. I had no idea how the whole GPS thing worked or fit into what I knew as IFR flying. Learning the 430 was a snap. And- they give you a cool little computer program trainer to download and train yourself- it is a very effective training tool. We have 2 club planes- one has a 430, and the other has a KLN94. Not sure what this says about the units themselves, perhaps more about the owners- but the 430 is ALWAYS up to date, the 94 has not been updated for a couple years. This seems to be a common theme I see: the Garmin owners are REAL serious about their equipment, the KLN stuff just occupies a slot in the panel.
