Love it! I bought new back in 1999, when it first came out. The S80 basically replaced my KX-88 + MEP4 combo that I was currently using. The S80 already has the MEP4 built-in making it a Great Master Controller! The key action is superb! Weighted,but-yet still fast. Very responsive AfterTouch! I recent picked up a Motif XS and was very disappointed in the sounds as compared to the S80. The S80 is much phatter, warmer, punchier and much more expressive than the Motif. Basically, it's going to be a very sad day for me if my S80 every croaks.
