I think you are very well prepared
. I would be more sceptical in Difficulty increase. If you can`t ROI within 3-4 month than you will not ROI even. Only if you will be able to sell used Miners for reasonable money to cover your investment.I can tell you that I like mining, but I stopped all already.
It seems that you believe in Bitcoin, then I would just buy and hold them. Use good cold storage or paper wallet. Make more copies and put them on safe places.
Thanks! How about this one:

This again is @3.4TH btw.
I guess I do believe in Bitcoin and with these numbers it's indeed not worth the effort compared to just buying a couple. I could shove the old gear down someones throat but that way I cannot enjoy a profit. Also, the way the price is going these numbers may be just as naive as the previous.
Do you know any pros in regards to difficulty-related miracles coming from next-gen networkpressure? Aside from the falling-price-factor, which btw is?, what's bitcoins 'critical hash? And when the net closes, which fish swim out first? How much fish are there anyway, and how big?
