Thank you torusJKL for a very helpful post. I was a bit worried about delivery date too after reading my posts here about pre-order nightmare so I emailed them asking their delivery date and no response yet.
For other choices in hardware, what do you recommend? I prefer add-in card like the Monarch because it's easier to have someone in US order 1 for me and ship to me in Vietnam.
I bought products from Friedcat (Block Erupter) and Bitmain (AntMiner).
They are both on this forum and only sell products they can send within days.
You should start a new thread instead.
