so a bit of an update on my situation.  I was checking facebook marketplace and I found someone selling 2 x M31S+ and  2 x Goldshell Hs5 units for $1500 each.  I am NOT joking and totally serious.  He did not know what he had.  Someone owed him money and offered these.  he took them and then tried to sell them.  I saw them and pounced.

Did I win the lottery?  First of all I cant find any of these units anywhere unless it is from ebay,etc for $8k++++

Remember I am entirely new to Asic mining (was a GOU miner for years).  These are my first units.  Did I get a deal?
