@mb190e, the discussion you referred to was one that I had actually started. I will say this, after I have gotten my beautiful Sophie, I am still confused over what makes a reputable breeder and what makes a backyard breeder. Even though you say you purchased Bruno from a person's home, you considered them reputable. If you had not gotten him from her home, where do others sell them from?
I live in Texas, and I have discovered there are many EBs for sale, but how you know the seller is respectable can be another story. I got my Sophie from an ad on Craigslist, which we all know can be shady. However, there are some groups on Facebook that specifically advertise EBs.
I'm not sure I would be so concerned about those who advertise. Like some of the advice I received, go with your gut. You will know what questions to ask, and if the answers don't feel right, move on.
