THANKS! ;)
BTW I did my own research and calculations of course.
It was the same one year ago like in these days. Everybody was crying on forums when Baikal released first miners: "They will kill Dash with that haspower!". Today it's the same.
From my point of view:
iBeLink - sold out immediately, difficult to buy
Baikal - extremely expensive
Bitmain - sold out immediately, difficult to buy
Innosilicon - with their selling philosophy will be reachable anytime
