I wanted to buy some new miners and was hoping someone in the group could lead me to a reputable vendor that has quality machines. I have bought 15 from a vendor on alibaba and it has been an absolute nightmare with these miners.

Hello I am rather new to the mining scene and this is my first post I hope I’m addressing to the right person lol.

Thanks
Jeff
