Buy motors for z-axis in europe

Hi,

I’m from Belgium, Europe, and me too, I don’t have a z-axis motor on my Maslow Machine, and would want to buy one.
Apparently in the Maslow store it is not available, unfortunately , as a separate part.
I saw some links in this topic on ebay and Amazon.com, but not realy sure if it is the correct , compatible motor.
Some of the links are no longer available either
Is there someone here that can point me to a source please?
Preferably a tested version, if possible, or clear specs.
Many thanks in advance
