Really, leaving only BM? Why do so many forget about Canaan?
Excellent reputation all around. Availability either direct or via distributors - check. Deliveries - on time. Build quality - stellar. Prices - decent.
Unfortunately they are too expensive for the efficiency they provide. Anything with a near 2y ROI because of their price/efficiency ratio is out of the picture for many. The newer ones are better, not a lot, but they aren't available till Feb, but even with that far out of a delivery date the 1168 in Feb is better than a 1066 or 1047 now.
The reliability issues isn't really an issue for most, it used to be but not now really.
