They need to update power info on the Neptune, it says 1200 watts for 3TH, I understood it to be around 22-2400?

Actually they just released the specs today that they hope will draw 2100 watts max. KNC:
"Upgrade cards.
We have also released 400 upgrade cards for those of you who wish to still purchase them. They are being shipped from stock and the first boxes have already left with UPS yesterday. Each card is now only 350USD plus shipping. You can order upgrade cards here
Jupiter 3TH
The window for conversions has now closed we have had over 400 conversions which means we are actively trying to fill all of the orders we have but we will contact customers individually if they are too far back in the queue to be converted. The good news is that the shipment for these orders will begin Tuesday next week after the Easter holidays and we expect it to take only a few days to have all boxes shipped out to customers.
Neptune Power Requirements
While we will not release the maximum performance of the Neptune miner we can now release the required power supply to give people time to purchase them. The maximum power draw will be 2100w of power and we recommend this to be either two 1200w power supplies or three 850watt power supplies. This does include a bit of a safety margin on our side and of course underclocking will be possible to reduce the power requirements even more.
Thanks
KnCMiner Team"
? price is way to high, with this price ROI = 3 months maybe more depends how much you pay for electricity, bitcoin price and difficulty, after that you will be making what ? $1/day --> 
you right.
