Don,
To the best of my knowledge, Meyers 200 do not have electric trim. The GFC500 can be installed without an electric trim. When the system senses trim is required, a message comes on the screen… “Trim up” or “Trim Down”, and the pilot has to manually adjust.
Regarding cost, or price, it is expensive. Each owner needs to determine if an autopilot can be justified through usage. I found it to be worth every penny and minute spent to have a GNC500 installed.
