The regular price is dropping rapidly, so in a few months the regular price will probably be 0.1.  I am looking at a return on investment of 1.5 years, and that doesn't take into account the increase in difficult.   I was hoping to pick up a few at 0.1 plus shipping to help with ROI.  I know it's my mistake for buying them at 2.0, but that's how we must learn sometimes.  I'd rather learn from getting it right the first time, but that's not going to happen this time.  Right now l'd like to buy what I can at 0.1, and save the rest of my bitcoin for something better.  I'll just watch the war of the 28nm pre-order ASICs heat up, and let's see who can deliver.
