SD10 vs DD15

[alctel]

Hey there,

Installing an autopilot and trying to choose between the SD10 (a rebadged octopus drive) and a DD15 (rebadged jefa drive)

Boat is a 36' Hunter 1980, 13500lbs unloaded so probably nearer 20klbs all loaded.

The SD10 is a grand cheaper than the DD15 AND it uses an AC12 rather than the AC42, saving another 500 bucks. It also uses 2/3s of the power.

However, I seem to be nearish the limit of the length suggestions on it, so am leaning towards the DD15.

Anyone used either of these two units?
