You are forgetting there are also:
KnC, Bitmine.ch, BTCGarden, Alydian and MyMiner.
True enough can discount Alydian late, Myminer and btcgarden had their ipo's canceled other two hmm well I know KnC should have mentioned them the avalon clone seems interesting enough

Thanks for pointing it out

(
I do acknowledge the hash rate is rising fast though )
if FC is currently paying $1.50/GH
where does this number come from? I've seen you mention it a few times, but I don't think I've ever seen where you got it. Did FC publish that?
Nope real number is $52/GH based on old gen I assume Vycid just put in a random number for the next gens cointerra is 3/GH though if we assume delivery in January 2013 in my opinion cointerra being labeled better than a BFL monarach on price per GH is kind of suspicious.
If this were the case ASICMiner would be selling USB Block Eruptors at a loss for
BTC0.1.
friedcat has stated that "
final margin cost for 1TH/s is less than 10k$":
https://bitcointalk.org/index.php?topic=99497.msg2013118#msg2013118The point is that Vycid's $1.50/GH estimate is a
minimum price, so using this in his calculations is only in favor of ASICMiner.
To me it's very hard to imagine that the cost per GH is less than $1.50. At this price we're talking $15 for a blade:

Not sure if I read it right on the $1.50/gh estimate or the USB miners
Clarification note:
Erupter USB $75/GH
Blade $52/GH
Old Gens
Although BTC Garden had their IPO cancelled, they are still progressing with their own ASIC design and hardware sales. I'm not sure if Myminer are still progressing, but I wouldn't count them out just yet.
Bitmine.ch have moved on from the Avalon clone service and now they have their own ASIC as well:
