If you have to come here to pose such questions, I don't believe you to be serious.
Look here and check to see if these latest miners are profitable now.  Then read this to see how other companies are faring.  After that, check out this bitcoin halving clock to find out when the amount you will mine gets cut in half.  Maybe you can cut a deal with the KNC bankruptcy trustee to buy their miners cheaply and have them shipped to you but I would be careful, once they begin selling miners again, they will probably fill their datorhall first (since old habits die hard) and then ship to you... it could be 6 months and many excuses later before you receive them.
