What a nice way to advertise your services, you mentioned all the pros of these 19 series which I would you second you on them, but why not tell them that there are a dozen people complaining about the PSUs on these gears? gosh, seems like bitmain doesn't want to make a perfect mining gear again, people always have to worry about a certain part failing when they have to pay 10k++ for mining gear, isn't it sad?
Well he did say get the extra psu and controller.
Frankly its a tough buy for me. I want 3-5 s19's but 33k to 55k for them with a spare psu and controller is more than I think they are worth.
My power deal would mean the buy of 5 doing 500th nets me 85 USD a day maybe 90.
so 55000/90 = 611 days
if my power was free
55000/180 = 305 days
so I am priced out of the s19 market.
