1.666Gh/s across 5 Block Eruptors and have 4 Drillbit USB thumbs on order at 2.7Gh/s each.  Been tempted to get some more BE's with the price drop, but can't justify spending any more money with no hope of ROI.  I certainly don't expect my hobbies to provide income, although it would be nice for it to at least pay for itself.
