I am looking to get started with a AntMiner L3+. Bitmain.com says "Coming Soon" for the last few days. However, I see these being sold in eBay & Alibaba for prices ranging from $800 to $4500.

Why would the manufacturer say "coming soon" but being sold by others. How is that the price is so far apart. I am confused and don't know where to start.

I would like to know the correct price for this unit and a legitimate place to buy one. Thanks
