Rob,
I installed two systems, an E95 and E97. I am very pleased with the systems, I like the option of the touch screen or control knobs. The set up and use was fairly easy, but I am sure you will hear it is not as intuitive as the Garmin. I put a full Raymarine suite of electronics on the boat - Radar, AIS, Autopilot, Chartplotter, so I have the E95, E97, P70(autopilot display), and an i70, that is pretty much dedicated to display depth. Everything integrated through the backbone seamlessly. I have created custom display formats, loaded waypoints and routes, created routes on the fly. all in all I am happy. I wanted to put in E125 and E127, but did not have the real estate. The displays are even crisper on the 12".
As always your mileage may vary.
Mike
