Congrats on getting them released! I have been waiting for this post for some time now. Mainly because I heard a rumour that you would be charging ~$40 per miner.
The pricing is the biggest disappointment for myself personally.
At 1.99 BTC, and a conservative estimate of 20M difficulty over the next year, it will take me 352 days to recoup the 1.99 BTC cost.
It difficulty averages 40M during that time, it will take two years to recoup your investment.
