The above point aside, you guys are clowns if you think these machines still won't make more money than you paid even if you get them 3 weeks from now..... Stop using Calculators they are dead wrong and have been dead wrong since the invention of them. The only thing that is relatively correct on them is how many coins you will get with the CURRENT difficulty (for however long that difficulty is)
Bargraphics, can you share more details on how you are doing the calculations? I have tinkered with several online ROI calculators and am curious to know how you calculate/speculate. I could use a positive perspective right now.
