If you buy Today your only Choices are Bitmain S7 or Avalon6. Choice is close with supporters of both, so you would need to read the Forum and make your own decision.
As to future releases of 14 /16nm based Miners, then you are in the land of the unknown, with difficulty increases working against you and the Halving getting ever closer. BW.com will probably be one of the first in the next Month or so, could be keenly priced? Bitfury may release something or they might not, if they do will probably be the most efficient but likely to be pricey?

On picking I would ask OP does he have 220/240? That is decent factor in which one is best for his situation. Also is noise a issue? this also is big on picking.
Also OP what is your electricity? That can help us see if ROI is even possible.
My apologies... I didn't know OP referred to me...
I do have 220/240v and noise is not the biggest issue. I would have a dedicated room.
Electric is not that cheap I guess... 8ct/kWh.
So... if I understand correctly... you all think the world of bitcoin is too far evolved for normal people to step in anymore?
Not at all. Anyone can step into Bitcoin. However to start mining one would need to invest a lot of money and it would be a huge risk to take. The best way to get involved at this point is to buy some BTC and hold it for a while. Either than that you can invest less in cloud mining but you will probably not reach ROI
I tried some cloud mining next to my little home mining and honestly the numbers didn't seem to move in the same way... I'm not sure how much fate I have left in that...
