Ok, I belived it's easier, but obviously isn't, thank you very much for such a fast and exactly answer!
I saw some people that sell pre-build, but it deserve to buy such miners or should buy miners like those from BFL? when I say if "deserve" I mean the price if deserve.
A good place to buy miners also would love, genre BFL miners, interesting me delivery time to be as little is possible. Thank you in advice!
I think that English is not your first language, and you might have a hard time understanding many posts. You should also read the subforum which uses your native language.
You should
NOT order from BFL now! They are more than one year behind in delivering orders.
You should look at the projects using Avalon chips, one named Klondike in particular. Many different chances to buy boards using Avalon chips. Avalon chips have not shipped, but there are some reasons to hope they will very soon.
I hope this helps you.
