When l bought the tub it came with an ST1000 which was obviously too small for a 5 ton (all up) vessel. Someone was "saving a few dollars" buying the wrong TP (TilerPilot). The animal.
After it broke - did not take long, as it was on its way out, anyway - the chap at Aquatronic repaired it and l flogged it to a Seabreezer replacing it with the ST 2000 which served fine until the boat was sold and it is still working, no worries.
It was only about 650 bucks or so. (at Ww at BoatShowtime, -15%.)

As the Raymarine unfortunately, is made in red China, l would buy the Pelagic instead today, regardless of the costs which is only a few hundred bucks, anyway.
The first thing l did was to make a spray cover to keep it out of direct sunlight and spray.

The main problem with the TP, in most cases, is not the machine itself but it's operators, who expect it to work beyond it's parameters.
The TP, regardless of its make, is a sensitive equipment not an Incredible Hulk.
Beyond the AutoTack function they must be used for fine steering not turning the boat more than a few degrees.
The manual says so, giving warnings of how not to use the TP.
The preference of wheel or tiller is personal, l am a tiller person.
Beyond that, like on the family boat a B523OC, the twin wheel is apt while on Rhapsody the tiller was the appropriate solution.
The big Benny would be impossible to steer with a tiller while the Adams's cockpit would be overwhelmed by any wheel.
I am an old sailor, no million bucks condo here, to boot.
