I was debating whether to order 1 or 2, but decided to order 1. Maybe the next batch will be faster or cheaper or both. I did not have problems with my Hex16Bs, hopefully I will not have problems with these, though 2.5553BTC will be difficult to ROI, but should be doable.
AntMiner uses much more power (about 1kW), so it may stop being profitable sooner.
Also I would have to pay 21% VAT and probably import taxes on the AntMiner. And I would have to explain BTC to the customs (especially if the price increases while I wait for the miner).
Also, "Shipping Date: January 23, 2014 (+-1 business day)", so, later than the HEX8A1.
Antminer does not use 1 kw. And its availiable now. It use araund 420w for 190 ghs.This marto product are still in prototype stage and chips are still not delivered. Further, it may be shipped from 10. February.
There is no import tax, only vat on declared value.
