Hi guys. That is pretty much my question.
Which firm of mining hardware providers is the best one?

I want to setup a mining rig (I have no problem with a free access to electricity) but I don't what hardware I need to buy. There are so much thing here: Antminer (a bunch of models), Bitfurry and other stuff. I have no financial problems and ready to invest 5000$ into my mining rig. Should I buy China or US made hardware? Which one is the best one?

Thanks a lot in advance of advise
