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!
