I post this topic to discuss what is the best mining devise to use for mining Bitcoin from home and what is the expected time period to get the investment back?
You want to mine bitcoin from home. My suggestion would be to use ASIC too, they are the only mining machines that can be used to mine bitcoin for now. Among them, buying Bitmain Antminer would be good. There are other products too but Bitmain Antminer has been the best.
You need to know that ASIC are miners that make noise very well. Fir your home, you may need noice reducer or war that is noise proof. The noise from ASIC can really be disturbing.
