Hi, Bob

But you could get into all sorts of strife with other chemicals around
the home. Paint, oven cleaner, shampoo, cement powder..... You
wouldn't stop cooking if you burned yourself on the frying pan once,
20 years ago

I have no problem using "dangerous" products like etchants and
oxy-acetylene. If you've got common sense, most products are only
potentially dangerous

That depends where you are. AFAIK there is no local service here
like AP Circuits. It would cost me hundreds of dollars to have any
board made. There definitely is a gain to making your own board in
an hour or two. By the time I've booted up Eagle or Altium, drawn
the schematic, laid out the board, routed it, written the email to a
board house, I could've probably etched my own and be soldering.
I've done it so many times I can assure you it is worthwhile for one-
offs that you want right now. Not so for repeat boards over a certain
quantity of course. Then you get the pros to do it
