Why the three months to shipment?   Bitbaza.com states that an order for the DM11G "will be shipped to your address directly from China through DHL/UPS" and "should take one to two weeks for your order to reach you" 

Of course, I don't like to pay any more than I have to, but if I can have my miners in hand in 1-2 weeks versus the 3 months for a difference of $750, then paying the $7500 to bitbaza.com is far better to ROI if deliveries are as stated.
