Janice - buy a new iron - they don't make irons to be repairable these days - it's a safety thing - they don't want any Tom, Dick or Harriet poking around making repairs and killing themselves. Just to get inside you have to destroy the iron.
Your threat to change Iron supplier has gone largely unnoticed.
Continual searching until you find an answer that suits you is a bit juvenile - but keep trying - you never know what might turn up.
Good luck...
