Excluding all other methods? That would seem to be the way it's been flowing
lately...

I don't plan on going to *any* engineers. The name of this list says
"Homebrew" and I figured that maybe I'd bump into other people here who were
making boards on a hobbyist basis...

Yeah, you already did, so I won't repeat my response here.

Seems like a lot of posts in here lately have been chemical, not either one
of the above.

Some of us don't. I for one have absolutely *no* interest in chemical
etching, and plan to do it with CNC once I can get something put together.
Is there a problem with that?

See above, the last paragraph I wrote above this one.
