hello. i have been looking around for some companies in usa or canada that are still selling mining machines. but i have not been having much luck. so i figured i would check with everyone here if they know a good company that is still selling machines. and what there web address is.
As far as US or Canada it would be resellers. Most gear is made in China. There are a few companies that break this though and have made other places their home.
But as far as "most current gen". There is S5 and Avalon 4.1 both are made in china and shipped from there. And there is SP20 gear it is no longer being made new so it comes from secondary markets all over.
As far as price S5 most likely will be lowest cost, but you will be shipping from China to get direct from Bitmain. Keep in mind if you don't buy direct you will not get the 90 day warranty.
