Out of interest does anybody know anything about Xtreme Miners?
They claim to have 3 machines coming out in Jan/Feb 2014? 2 of them are listed as faster, cheaper, and using less power than the Neptune, whats the catch?  or is this a scam? Please does anybody have any hard facts or advice about Xtreme Miners machines?
Any advice most appreciated.

Hey guys, me and some friends are currently pooling a lot of $ to start accuring machines to start mining crypto currencies.
Researching everything is proving a real headache, one forum may say something is great, yet another site will say its a scam. We have already ordered a Neptune, but does anybody know anything about these Xtreme Miners, allegedly they will have 3 machines coming out in jan/feb? 2 of them look faster, cheaper, and use less power than the neptune, does anyone know what is the catch?
