Hey Monkey,
You say Cointerra is overpriced. Well, ive ordered hardware from some of the other companies (knc, bfl, hashfast etc) and i cant find anything cheaper than Cointerra, per GH right now. Do please tell me what youve found that is cheaper GH than Cointerra as id like to buy some?

There's a big difference between say $4/gh received in September and $4/gh received in January. The former is probably 5 times more valuable. Thus, there's more like an equivalency between $20/gh in Sept and $4/gh in January.
You obscure that fact by completely ignoring the time factor, the most important factor of all in hashing hardware.
KNC's gear may be more expensive per gh, but it's also coming months and months earlier. You'll be lucky to even achieve positive ROI with a Cointerra rig, even at their lower price. And if they ship late it's all over.
