I'm actually looking to pick up at least 1 S9-performance-equivalent miner, just to keep a single system mining for the principle of it, to go along my full node and LN node.

Don't want to support Bitmain.

Doesn't seem I have any other options available to me at this time.

Here's hoping those products out of Japan come online soon, or dare to dream Bitfury ever reconsiders coming back down to earth.
