I don’t think the Innosilicon A10 is a good buy at this time unless you picked it up for $800 dollars, and no one seems to be currently selling them that cheaply.
Ethereum wants to move to proof of stake, sure, they also are considering moving to ProgPoW, but they’ll probably continue to try and drag that out until they can move to a hybrid PoW and PoS model …
But anyway, to the point, over the next year at current mining profitability figures for the Innosilicon A10 on 10c per kWh electric rate, you’d earn $1200… so if you paid $1200 you could only hope to breakeven on it within the next year… I’ve heard some rumors these miners could have issues with the DAG file by the end of the year too.
Ultimately this miner is too expensive for me, and earns too little, to recommend buying it in this current market and at relative current prices

If anyone is interested in checking out the video that @louisswart referenced, here’s the VoskCoin review on the Innosilicon A10, that miner along with the Bitmain Antminer E3 have been killing GPU mining profitability for quite some time now.
