+1 not to mention we have a new player on the block that can ship you 800gh for 18btc within 2 days... i'd say 12 btc is a reasonable price for batch 1 KNC miners..
While I would agree the batch 1 Jup's were worthwhile to the original buyer if they spent USD on them, 60 day estimated payback covers almost 6 difficulty changes. Its hard enough estimating two changes out. When HashFast delivers you will see that 60-day ROI turn into infinity.
