Thanks for your response AKMiner. There are 2 online retailers offering the Z1+ for $4200, includes PSU and delivery, i.e. Asicminermarket and Estrahash. If you can charge the same and also allow me to add trade insurance i will gladly buy this product from you now
First we don't have trade insurance because we are single website not list on aliababa(trade insurance available on alibaba).
second for price you can going to
www.akminer.com direct contact with owner to see if it's works for him, I am not sure such low price owner will accept it, however why not just have a try will save money why try it first.
