Ok... I took the bait and purchased two 1.2GH/s miners for claimed delivery on February.

I am making the assumption that they are legit based on the endorsement of bitmine.ch who I'm also assuming is legit.

I also believe that bitmine and AMT may deliver ahead of hashfast and cointerra based on an earlier tapeout date.

Finally, looking at the AMT product line, it's clear that they have existing products that appear to be based on the Bitfury chipset.  

These folks appear to be resellers/assemblers for Bitfury and Bitmine, so it is not like they are conjuring up their designs from thin air.

So at this time, I am giving them the benefit of the doubt.  After all, what other options are out there?
