I sent an email to CryptoHardware.com inquiring about their Baikal Giant B miner and here is their reply:
Hello and thank you for your message,
Product availability for Feb 10:
Baikal Giant-B (5 units left and 2 unpaid yet)
The price without PSU will be $6140
Just add this coupon in the checkout page. hzsgjezx
We need 6-12 hours of testing your device to avoid failures.
After shipment registration, I will send you tracking number and scan of the receipt.
Which delivery service is more preferable for you?
UPS will take 5-7 days to US
FEDEX will take 7-9 days to US
We will specify in the description: "computer case" and value: "USD 140-160".
So there will be no problem with customs and taxes.
Please let me know.
Kind regards,
David Colbert

Their price has since come down to $5400/unit for the Giant B.Not enough info / feedback to confirm if this site is legitimate. They only accept Bitcoin, BitcoinCash, LiteCoin, and Dash. They are located in Portugal (outside of U.S., if that matters). Dunno is they provide escrow service.
