I was referring to the cointelegraph article. There might be a reason why they did not include some of the anonymous pseudo companies in their review  Ltcgear is anonymous and they could run any time with your coins. Not even registered a company last time I checked, so hardly legitimate business. I hope not too many fall for these scams.

MAT? Did they ever deliver any product?? Maybe you want to add Fibonacci to the list, too. I heard they promise a great ROI  

Please also update the numbers of scrypt.cc - they are outdated. Effective price is 8 USD cent per kH/s.

At least, we agree on Gawminers, but they are just on par with GM (as we have recently discussed here). You should calculate the effective cost of ownership.
