I'm interested as well and will purchase numerous ones pending performance numbers of course. Funds are ready whenever the design is. For me electricity isn't a big deal being I pay $0.09 KW/Hr which is pretty good considering that power+line delivery costs+taxes
Just thinking out loud here, but are sure that hyper-efficient litecoin mining wouldn't actually kill its value?
Depends on what the miners did with them, some will sell just enough to cover the bills of operation, electric, personal time, etc. While some may keep dumping and yet others will hoard every red ltc earned... naturally if there are more of the first and last kind of miners you'd expect a price increase regardless of the economy growing for ltc, if most of the miners are in the middle group then it all depends on if the ltc economy grows in terms of businesses/services/demand accordingly....
In any case I'm willing to bet the first scenario is very likely...
