I have seen lasers that appeared to be able to focus their cutting
depth. This would eliminate the concern about buring the substrate.
However, I know nothing of laser cutting/ething machines. IMTS is
comming up in fall of 2006, that is always a great place to go to
learn all about machine tools. Hopefully I will have time to go
there and nose around.

No doubt about it. I am just looking at all the options and
possibilites and making sure I am not "missing something" obvious.

Your right, no point. However, fears are often not reasonable or
logical. I have a fear of heights - what the hell? I have flown
hundreds of thousands of miles in airplanes - yet I don't like being
on a 10 foot ladder?
