Hi group,
I found an SDX for sale comprising three ZI pads and one bassdrum pad, all white. You can dig it in the small adds here:

It is located somewhere in southern Germany. It doesn't say anything about the price ("negotiable") or even shipping. But perhabs for somebody the chance of his (her?) life
Best regards
Wolfgang
