is this site reliable?http://www.antminerdistribution.com/
Never dealt with it. I personally would get direct from bitmain if your wanting a new machine. It honestly is best way.
If you are wanting used look on forum here or ebay is other two options.
no i do not want used miners and propably buy from bitmain again the only reason i asked was because the site claims to be fromEU and it is more easy for me to send them money bacause we have capital control in greece.
