I'm with you.  I've been through the paces and experiences with the hardware (GPUs, ASICMiner, BitFury, BFL, Bitmain, etc) since early 2013.  I've also had my bad experiences with Bitmain.  In my opinion, however, the T9 is still be best deal today at around $108/TH (0.126 J/GHs).  The S9 13TH is around around $122/TH (0.098 J/GHs).  The newest Avalon 741, however, is very competitive at $112/TH (0.157 J/GHs).  Not much of a difference in the short run...  However, in quantity and over the long haul the cost diff can easily add up.  Who knows,  I may also jump to Canaan.  Time will tell.
