I don't understand all the love you guys show for Bitmain. Yes, they have delivered. No, their price has been reasonable, but not good for us miners.
Donno, my last few S1s that haven't reached breakeven will do so very soon (and that's with paying Swedish VAT on them) My first batch are sitting at around 20-25% profit in BTC (what more could you reasonably ask for?)
Rograz, now that Bitmain has become an established company due to the support of miners and what appears to be a good business plan. I think it would be reasonable to ask for 35-45% RoI for miners(market dependent and before VAT).
I suspect based off of the miners I have received, and posts I have read of other forum users that Bitmain doesn't just stress test(QC) units before they ship but actually uses them until they ship, then ship them as 'new' at a 20-50%(decreasing as the hash rate increases) markup on their manufacturing cost. Thus netting them miner and markup(double return) of 60-80%(guesstimate). Granted this is just speculation(like most of this thread) but it is by no means a crazy leap of logic.
I also don't begrudge them this business model, I think its a smart way to RoI, however I would like to see slightly more on our(miners) end of things.
