I ordered many gridseeds from Jack, no problems.
I ordered a A2 LA90 from Jack and I had it here pretty quick, Think it was 3 or 4 days.
Pretty sure Jacks price for the LA90/A2 is the cheapest out there. If not just get him on Skype, He will work with you.
If ANYONE is looking at other miners, Z or G or H or anyone else, please note, the POWER usage on them is HORRID!!
The A2's hardly uses any power!

Yeah Z fucked us over pretty good. I think the power consumption is 3-4 times what they promised. Users report PCI-E cables melting. A lot worse than Gridseeds, not to mention A2.
For what its worth, I ran the LA90 A2 in my hot Florida garage for 2 weeks before I put it in my rack in the datacenter.
My Garage was 91F 24/7, the A2 ran just fine in that heat...

Now its nice and cool in the datacenter.
