Goodmorning guys,I want to add 100 more TH to the pool and I am trying to find the best miners to buy,so I have 10 t9+ and 1 m3x,lets forget about the power comsumptions,the m3x is a beast and stable as hell,the t9+ is just cheap and 2 of them are mining at 8 to 9 Th instead of 10.5,I haven't tried yet the avalon 841 or the S9i,wtf should I buy?

Avalon miner 841 without psu 13TH 1120 USD
Pangolin miner M3X with psu 12.5TH    850 USD
Antminer S9i with psu 14TH    1010 USD
Antminer T9+ with psu 10.5TH    635 USD

I have been slowly buying Avalon 841's from Blokforge. I am about at the limit of power availability at my house unless I get a second meter and power feed installed.
The A841s seems to be stable. I have had bad luck with the S9s and S7 from bitmain. The S7LN's seem fairly stable, probably due to their extra cooling fins installed on them by bitmain. The case for the S7LN is about the same size as the case for the S7 but it is slotted for only two cards and the cooling fins fill that extra space up. The problem is they only produce about 2.7THash/sec with a power consumption of close to 1000 watts. I only run them in the winter as they are not very efficient. You can get around 3Thash/sec out of the S7LNs if you goose them up to 700MHz, standard is 600MHz. I did that to the ones that run coolest.
