scream for some screens
David-I too have and O'day 28 but I am blessed with perfectly good screens in the head area. The salon has similar PYHI screens and ports, just slightly larger. I had to replace them due to old age (of the screens) and ended up with a Washington state chandlery. The screens he sent, NO REFUNDS, are the wrong size so I ended up using strips of double stick foam to hold the screens in place and it works good enough for now. I am told that Rudy has screens. Give him a try.Good Luck,Mike
