I am currently selling a fully functional guardian farm (does not use soulsand). It is set up to auto kill but I will change it to manual kill for an extra fee. The price is $400k but there is room for negotiation, although the price can be earned back after grinding for a few days. I’m only selling this because my town has two. There is also a large sugarcane farm above the grinder along with a few cow spawners, they come with it.
