Hi Pete
Eddie Here.
That was my first Brand New Dishwasher back in 1981. The Cleaning that the machine performed was superior. It would take the Chrome off a trailer hitch. Yes, The drying was not good, but it cleaned like a "White Tornedo".
If I found one today, I would buy it as a back up.
My "New" KDS-20 is cleaning like all get out, but I still remain True to the KDS-18. Which I'm going to replace the timer in tomorrow.
