If you don't mind spending $3,000 on the lottery, you can buy this model for solo mining and mine for more than 1 year.
Buying this model to recoup your investment in 2 years or more makes no sense.
Its not 3000$ , but understand your point.
At 16j/Ths this miner profitable also mining pool.
It wound be everybody cup of taste indeed. Industrial grade is slightly cheaper price per Th/s
