I know they are not profitable but I would like to play with one.
Preferably a used AntMiner S9 or Avalon machine.
Where are you located? NA or EU? You need to give some details otherwise shipping estimates cant be made - a key factor into deciding if it's worth selling.
Australia
I've been looking at the smaller V9s for my project, although not sure what else I need for it. The s9 models even here in Aus are way overpriced for machines that can't make profit here in my view. Although they are good. Maybe worth the typical ~$500 price tag if you buy lots and co-locate overseas I suppose.
Anyway regional Australia.
