My Dad flies 172's, a 172RG, a 182RG, and a BE-76 Duchess. The Duchess and 182 have Garmin 430's. The 172RG has a Garmin 530. The 172's don't have GPS', so my Dad is thinking of buying a Garmin 396 Handheld. It is basically the same as the Garmin 530. It just has a smaller display but it does have the ability to upload your flightplan from your Computer.
