I've been looking for this miner also because its very quiet but most that I find for sale cost more then a brand new S7 in terms of Th/$.
They got like a 7 months ROI with free electricity.
Ask for droid to sell to you instead of me then, his price is pretty acceptable imo. I'd pick one up but i'm dry on loose funds as i picked up a S7. And it doesnt really beat getting undervolted S3 in term of ROI.
What's he asking?
I figured you'd ask him directly. Well to hell with it, he said he could offer me one for 0.65, you're more than welcome to PM him and ask him if that price is doable for you. I pretty much told him my budget for these don't extend over 200$ even though i recognize thats a cheap ass price.
You won't find one in that range. These still are not bad machines. They had premium for the quiet vs buying bitmain at the time. And they have a huge ability to change speed.
.65 I think is pretty fair if anyone is wanting one of these. Someday when I sell mine I likely will try to sell my set of 3 at once. But I will mine with them for winter most likely.
