I find out the company that has the good deal for the group buy on Sun hyper voltage system. Min 10 pcs. If I can get 10 people to buy with me, the price will be $158.00 / pcs shipped (48 states USA mainland). $10 more for Hawaii, $18.00 more for Canada.
They also have the Hyper Ground System for sale:

Here is the manufacture web site for this product and they have the MSRP.
