I agree...
The autopilot in my boat costs about $900 CDN.  It uses fluxgate technology,
and with the $900 CDN you also get a waterproof control box, large servo motor,
and the mechanical stuff to tie it all together.  It has +/- degree controls
so it must be fairly sensitive, although it just works relative to
the last position, not absolute with respect to the earth.

I would be curious as to where to find just the sub-assembly.
