There is a good guide worth downloading here

http://www.windpilot.com/

click on the link that says self steering under sail, 7.4mb pdf file. Its
well written, independantly and gives a good overview of general types of
windvanes (horizontal versus vertical etc) and specific comparisons and pros
and cons as well as the evolution of different manufacturers. It has some
info on autopilots as well, but it should give you a bit of an overview.
The consensus seems to be that a windvane and an autopilot each have their
purposes, but for longer ocean voyages on anything less than a modern
ultralight mega racing yacht, you'll probably use the windvane most of the
time. Most boats would do well to have both if you have the space and the
budget.

For myself (thunderbird 26, mostly coastal single handed cruising or with
one other person) a windvane is what im aiming for.

There is some other good info on self made windvanes at these addresses

these are worth a read even if you arent going to build one yourself (id
reccomend not building one yourself!!!) they can at least give you some
understanding of the advantages and problems inherent.
