Fairly recent convert to cryptocurrency.  Time to stop lurking and get active...kicking myself for not paying attention when I first heard the term bitcoin.  Currently mining the three primary currencies on a couple 7950s and a block eruptor (yes I know the ROI is terrible). But with a couple pcs that are normally on 24/7 anyway I figure a couple additional watts for some coin.  I figured i could stay home from the bar for a night and save enough to justify the Eruptor.  Looking more to mine and hold than to turn a quick profit anyway.

Any tips or recommendations for the the group buys on the big ASIC rigs?  It Seems to me that some of those have great potential for decent Ghs/$ even with some conservative forecasts for difficulty adjustments.
