The fact is that the MZ2000 was really a Technics keyboard to which Casio added the drawbar option and the microphone input, all the rest was identical to the Tehnics model (that still was twice as expensive). Probably Technics was even making the boards for Casio and put their name on it.

But now Technics completely witdrew from the instrument market, so perhaps Casio can't get them anymore.
