Chet,I've used the OLD Autohelm AH4000 Wheel Pilot for the last 14 years on my 37C. The only problem I had was a broken clutch lever. I ordered a new one over the net ($5.00) with Prompt service. Just last fall, I started to have intermitent problems with the control unit. So, I just recently purchased a new ST4000 at Boat Show prices ($750.00) with no remote. Wished I knew aboput your $670.00 price. I looked at the Simrad and agree that it is speced for a little bigger boat. The new ST4000 is speced for a little bigger boat than the AH4000, but less that the Simrad. I went for the ST4000 because:1. Good history with my AH4000.2. I have received my new wheel unit and inspection shows a much better design than the old AH4000 wheel unit.3. I, also, bought new wind, speed and depth instruments which will be interconnected using "Seatalk". I will also interconnect with my Garmin GPS.4. I have the flexibility to install the control/display unit anywhere I want. (Which will be on the pedistal above the compass).DOWNSIDE points:1. More wiring. Flux gate compass and control/display unit all mounted separatly from wheel unit.
