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.
