I think this list encourages fraud.

There are only two companies in your list that have actually shipped:

BlackArrow and BitFountain.

The others:

KNCMiner - science fiction story, they have not shipped anything they do not even have pictures of their products.
t13hydra, terrahash, ryepdx, burnin - rely on avalon ASICs which have not yet been produced.
Butterfly labs - have taken orders of millions of dollars, have not shipped in 1 year, most likely a fraud.
