So that you all know, My friend Steve at S&T Avionics in Sister's Oregon did the install for me and bought the Dynon stuff via Northwest Avionics in Sisters as well, from Marc. In my opinion no one is better than these two. The Garmin and PS engineering was purchased through Layfette Avionics, who were great as well. Lost around 35 lbs. off the front of the plane, and best of all, no vacuum pump! This avionics upgrade was the best experience I've ever had working on airplanes, I can not say enough good things about these guys.
