maybe you havent found the cheapest source or are willing to believe they run at 3.5mh. regardless of the price you buy at or exact final mh they draw significantly less power (70w compared to 1100w). the heat generation is another reason to go for this asic. i dont believe they will become paper weights anytime soon, gridseed are struggling to keep up with orders and scrypt coins will be around for at least 12 months, enough time to collect roi. increasing fixed start up cost only moves roi out by a few weeks.
apart from gridseed there are a number of companies you can google that will release 18-40mh miners in the next 3 months (fibonacci, zeusminer, alpha technology etc..) that will render gpu mining obsolete, exactly the way it did with bitcoin. i would recommend not building any more gpu rigs while those gpus are still worth something and dont become paper weights
nah alpha is like 6+ months away like most all of the others just like the alpha unit it is still more expensive than the equivalent GPU rigs, I have been following them and alpha in particular for the last 3 months alpha is still in the design phase no way they are getting anything out before October this year.
so again you are incorrect they wont render GPUS useless like the scrypt miners for BTC, the miners for BTC hashed
MUCH faster at a MUCH lower price than GPU's all the SCRYPT asic miners cost more per hash than a GPU rig but save on power that you may or may not recover in time.
and I can go out NOW and buy 40mh of GPUS and start start hashing making money today instead of giving it to a company that may or not run off with my money or even deliver my product on time ( remember BUTERFLYLABS)
so completly different to BTC ASIC miners.
you say I have not found them
well please show us a link where I can buy 10 x grid seed units with power supplies and accessories for $2300 USD please do i say you are full of BULLDUST
