Looking into Avalon Clones a bit, there are a few flags that raise questions: they haven't demonstrated a working prototype; there is no personal contact information on the web site; and they said they had two funding rounds so won't need to do pre-orders in their press release, yet are requesting preorders on their product page. We'll continue to watch it for developments, but at this point I dont feel comfortable putting it on our page.
They posted a thread about it here. I don't think they're a scam in the sense of not actually being able to build their clones, but rather in the sense of charging
way too much money, hoping to sucker the less savvy into buying mining equipment that will never see a positive ROI unless the price of bitcoin skyrockets again.
Thanks for the suggestion, I changed the Cost Efficiency column to reflect $/GH.
Cool!
