Thanks to the mod that moved the topic and sorry for posting it on the wrong thread.
The only way I see to get what I want is to buy an Antminer S9 on Amazon, unfortunately.
I was aiming for an Antminer S11 (20Th) or a Chinese Aisen (or Aiden) A1 (24Th) for less than €400. Just because they eat up a lot of power and therefore aren't profitable.
The miner hardware market on EU seems really short, is it because of electricity costs? There are really few options here...
