I suggest you research what's best for you, as electricity consumption and connection speed are very important before putting them to work. There are groups on TG that offer various options and teach you how to maintain your miners; you decide what's most viable for you. Personally, I can't have one because my connection is very unstable unless I buy one and put it to mine in a farm, paying for its upkeep and maintenance!
