tip: doesn't Bitmain usually advertise them self , when they do world wide sales ? .... or they have in the past even for used junk . just saying 
nothing more I'm sure bitmain is selling these 5k plus units but id hold off ...
an what ever happen to the faster they got the Less Electricity they used by that I mean miners doing lets says 15 th using below 1 k watts or 900 watts ...... or 15 th with 900 watts @ the wall .... well anyway i knew that was a pipe dream, right now. they do indeed use less now but I expected better power usage by now . but then again they also don't make home miners either like they did once upon a time or when they first started it out . just my 2 cents worth .

I would love to see a new version of the R4. I think a sub 1000 watt draw miner would sell very quickly here in the US for the entry level miner. Hell when they come out with the 12nm or 10nm chips, make like a "mini" version for the hobbyist that uses 1/2 the number of chips
