I finished cleaning and calibrating the MS-20 a few hours ago. Now it works like a new unit and the overall cosmetic condition is impeccable. From the look of the keys I can see that they have almost never been touched, I only had to polish two black keys and that was it!
This is so much more fun than the MS-20 mini, which was shrunk to 86% of the original size. Full size is really what I need to play comfortably. I won't miss the mini too much. I am going to sell it soon.
