Up for sale is my trusty Kurzweil PC88MX. Full disclosure - it's beat up. The outputs are noisy at times. The left output used to cut out, though it hasn't in many years now. I did nothing to fix the problem - it just started working again. The keybed is squeaky, as is always the case with Kurzweils of this era. A few of the keys in the low range have iffy contacts. They'll frequently hit at max velocity even when you're barely pressing the key. While it's still functional, I strongly feel this piano is best suited for someone who wants to fix one up *or* someone who has a PC88 already and is seeking a parts keyboard to keep theirs running.
