Catherine, I have 4 optacons; one is an optacon 2 and the others are R1D machines. One was purchased for me by my former employer and they said I could have it when I retired. The other two are machines I bought before my employer bought me one; I used one at home and one at work. I bought the optacon 2 because I found out we were going to be using color displays and I thought I would need a newer model optacon to read the screen.
