Creative, I believe you are one of the most communicative and capable members around here who run a bitcoin mining related company. Unfortunately, I do not believe that simply buying hardware from 3rd parties in an attempt to maintain network percentage can be profitable in the wake of monstrous difficulty increases. Have you ever considered expanding from simply scouring the internet attempting to find cheap 3rd party hardware to actually taking the step in taking part in the manufacture of your own ASICs?
