I placed on order about 10 days ago with ZigHash and had an excellent overall experience.  The shipping was extremely fast.  I was in communication with Jacob and he let me know exactly what additional things I needed (PSUs) and what to expect as far as shipping times.  He even gave me some recommendations on pools to choose.  I would give this seller an A+ rating, would recommend him to a friend, and will be doing business with him in the future.
