Charles,
The astrofocuser is an excellent way to focus using long
focal lengths (telescopes).  It is useful for focusing on starlike pinpoints.
I don't have any experience using one however.  You can, however, make
a knife edge focuser using a some tape, a plastic cd case, and a piece of unexposed film.
It is simple and cheap to do. And the most accurate way to focus a telescope.
If you are interested in making one, I will dig up a link I came across which
shows you how to do it.  It's really quite simple.

Regards,
Grant
