The only way to get information past pointless smileys is to contact him. Since hes unable to tell you, I will:
Under 15 units, for testing, its the same price as 1 antminer s2. Since i looked up the price on ninjatech.org and it was stated as 7 btc, so ~3200$… jbcheng said it would still cost 3599$…

@jbcheng: could you be so kind and answer my question regarding bigger volume prices? Still waiting for an offer.
