KnCMiner is still in the process of shipping Neptune Bitcoin miners, but now offers cloud hosting. One cloud hosting package gives you 3TH/s for less than $1,000 per month and you do not need to pay for power. Neptunes cost pre-order customers $12,995 and also give you 3TH/s, but you pay for shipping costs, a PSU to power the unit, 16AWG cable upgrades, and power consumption for running the machine. Neptunes only recently started shipping and very simply, most Neptune customers lost five-figure sums of USD by pre-ordering instead of waiting.
