Hahaha nice 
But... G-black is 2099$. Hashrate is 25Mh/s, so it's 83,96$/mhs... not really a good affair, in comparison the Zeus Thunder X3 is @ 1999$ for 28 Mh/s, so 71,39$/mhs...
But your G-blades prices are nice, 399$ for 5,6 Mh/s (you're the cheaper seller on the interwebz, GG
), it's 71,25$/mhs, better go with them
