Spondoolies-Tech has a special holiday offers for their smaller 1.7 THS Bitcoin ASIC miners targeted at home miners – the SP20 Jackson. The units are shipping from stock and a single SP20 Jackson is currently available for $659 USD, a three SP20 Nano Farm miners pack is available at $1900 USD with free shipping included (~$633.33 USD per miner) and a 15 SP20 Mini Farm miners pack is available for $7995 USD ($533 USD per miner) with free shipping. Do nnote that the SP20 Jackson miners do not come with power supply included and a good 1200W PSU is recommended for each of the miners, so you should count these as well when doing the ROI math.
Spondoolies-Tech also offers a bigger Bitcoin ASIC miners in terms of hashrate, these are the 4.9 THS SP31 Yukon available at $2595 USD and the 5.5 THS SP35 Yukon available at $2795 USD. Thse miners however are targeted at larger mining operations, though you can consider them as an alternative to the packages including multiple SP20 Jackson miners as they do come ready to be installed and used – with built-in power supplies. At the moment Spondoolies-Tech probably has the most power efficient ASIC miners that are available to order and ready to be shipped.
