Guys, my partner found a supplier for a AC adapter that should* work well for the Z.
It's a Astrodyne PSA05R-050.
Input voltage: 90-264 volts
Input Frequency: 47-63 Hz
+/- 5% regulation
... lots of other good specs (can't seem to find them on the website though).
And you can get whatever adapters that you need for your country.

Edited: Oh, and they are 5 volt, 1 amp and cost $24 bucks each.
Edit #2 Oh, and you will have to make sure that the plug fits (it looks like it should, and it is polarized correctly according to the specs).
