little birdie says . . . between 40-43K USD . . . MOQ . . . around 15 units . . . Delivery around March 2016
So.... $377/TH with a 5 month leadtime (inc PSUs). S7 is $340/TH with a <1 month (no PSUs).
The lead time is a killer, but tit for tat the SP50 is a much better solution for large scale farms.
