So there are no other setups that would cost below 15K and would actually ship before March 2014 (and turn a profit)?
What about the Black Arrow Prospero X-3 or the KnC Neptune?
Neptune is only profitable if it ships in Q1, anyone who gets one in Q2 will be SOL and barely be able to make their investment back. Anyone who starts the Neptune in April will start making negative BTC by the end of July. They will have made $8000 worth of btc minus $13.5k of initial investment, so Negative 5500ish. Once they sell their Equipment, they might be able to come out even or probably a little ahead.
The ONLY offset to this is if the difficulty doesn't grow as fast (unlikely) or the value grows by 50% per month in the next 6 months. (Highly, speculative, insanely actually.)
I don't know about the other two, but the knc neptune is a bust unless it gets here in january or february. If they could say "Guaranteed Q1" I'd be on board.
