I am a volunteer braille transcriber and am just completing the textbook course using EDIT-PC. I am considering buying Braille2000 and want to be sure I am ordering the correct version. There is the Basic Edition for $359, Direct Entry Edition for $619, and Document Processing Edition for $949. I'm guessing that what I need is the Direct Entry Edition. Can you give me advice on this, or know who I should be asking about this?
