Our S17Pro is operating at 2/3 capacity. Last month we had a chain of ASICs become non-functional. I've been quoted a price of $300 + parts to have it looked at and repaired, but I'm not sure if it is worth it at this point as I had been thinking about selling the unit to upgrade to S19 hardware. We have quite a bit of funds sitting around that would make this $300 a non-issue, but I feel at this point in the Bitcoin price cycle it might be wise to just let things go as they are and wait for an opportunity to put our funds to use.
Great news! We were able to have our non-functional board repaired free of cost by one of our fellow helpful NastyFans members! Our S17Pro is back to mining at full capacity and I'm sure this will help resale value along with higher donations if it continues to operate normally.
S19's are in pretty high demand still. They're currently selling for 3x the retail price and if you want to pay retail they are sold out. If you were able to get an order in with Bitmain you would be waiting more than 6 months for delivery. For these reasons we're still plugging away with what we have and enjoying the increased value of BTC in our savings while we wait for the right opportunity for expansion.
