I finally decide to get a Minox DSC silver. The reason is the lens. DSC silver does not share the same lens as DSC black. It has a fast F2 lens vs F2.8, hence a full stop faster. Optically DSC silver lens is the fastest compare with all Minox 8x11 camera's f3.5 lens. BHphotovideo has the best price +shipping. Although Adorama lists it at the same price, but with much higher shipping cost.
