Hello from Barcelona, Spain:
I bought my VFX-SD in November 1990. In those days, Ensoniq products were not very known here, and I remember the \u201cfeeling of risk221; when I paid the approx.equivalence to $2700.
I send the VFX-SD to repair (calibration error, keyboard wiringR30;) two years later, and it keeps working OK since then (still with the original battery). I had to replace the internal fuses several times.
In the last days, it hangs sometimes (system error 144 or so) but usually it works again after re-initializing.
The only problem now with the unit is the Data/Timbre slider: it is almost unuseful because if I move it, numerical values start to increase or decrease randomly, so I must use the 2 buttons instead.
I hope it will keep working for long years!
Hasta pronto.
