Amen Robin!
I agree and have always felt that the whole ROHS clamp-down was driven by
the European Union as economic warfare against not only third world
countries, but
against any competition from smaller companies everywhere. Phillips
developed the
non-ROHS technology first... and ~then~ coerced the EU into making it
mandatory so
that they could have a jump on everyone else. "You do Love the Earth,
Don't you???"
