hi all we are a group of friend that would like to invest up to 15'000 $ in mining hardware...
any suggestion? imagine me ... is one week i'm freaking around comparison, possible fakes suggestion and questions to producers...

xtrememiners seems to be the best in term of cost / hash / power (but probably a fake)
than we have kncminer.com with his neptune but is costly
than hashfast (trustable?)
![Huh](https://bitcointalk.org/Smileys/default/huh.gif)
best news might be that i'm wrong and xtrememiners is not a fake... but i doubt it.
any suggestion?
