It took a while, but the premium Garmin VHF 200 is now a reality, and it's a corker. I installed a sample on Gizmo yesterday and spent a fair bit of the day listening to it and trying out DSC features.  As Bill Lentz noted in a recent comment, the 200 is a snap to hook up using NMEA 2000, instantly getting GPS off the backbone and delivering DSC call info to any device that knows what to do with it (unfortunately few so far). It also seems to have a sensitive receiver and a nice way of pausing enough in scan mode that you'll often hear both sides of a conversation.  But he didn't get into how well the soft key scan (and other) menus work...
