I bought a millennium 20--I may have mentioned this before. I just figured it would be in all respects except new features and display like the Braille lite 18. To my horror, I discovered that the keys are too noisy for me to take it into quiet places like church services. Does anyone know if buffers or something like it could be put in by somebody really comepetent to make my millennium 20 quiet as my braille lite is? thanks. Penny Golden pgolden@xxxxxxxxxxxxxx
