I agree that one must trust one's own ears & eyes. The problem is that no local dealers carry the model MZ-2000.
The web site demo was interesting - and I couldn't really judge the sounds as they were downloaded and played through my computer sound system. I was curious about "Zygotech Polynominal Interpolation". I couldn't find any reference to it on the 'net.
I have read some glowing reviews written by UK owners, and it may be a winner. Who knows? The next "got to have" may be a Y2K Casio.
