Also, as has happened with others, there just arent enough margins to give everyone more hardware to compensate.  Its not like these things have 100% margin so you cant just double up the supply.  Those days are long gone (avalon maybe even kncminer had great margins, the first time around... but the more recent asic companies have operated on much slimmer margins... and their costs are high because every part theyve ordered has to be on a 'rush' schedule which means everything costs a lot more than if you could give the suppliers the usual 12 weeks to source the parts (an eternity in bitcoinland)
