Thank you to djeZo for frequent updates here and improvements to the site.  I am watching the rigs list with great interest.  So you're looking for sellers to lower to 0.02 BTC/MH/day , is this based on mining a certain coin or on figures plugged into some profitability calculator?   
About pricing, is this for real?  0.0444-0.0464 for Thrash user...why is it over 2x your recommendation?  Either I am misreading it or something is wrong here
