Just as a point of interest, my wife uses her braillite-40 everyday. We replaced the batteries and charging circuit with more modern ones about ten years ago. She really likes it and is always worrying about what she'll do when we can't repair hers any longer. It's editor is clunky but beats the shit out of the editor in devices like the Alva units.
