I agree. I have to laugh when I contact people to buy a domain name and they offer that we get an automatic appraisal. This shows weakness. As a domain name holder, you should have an idea of what it is worth, and if you dont, then I'm probably going to pay you pennies on the dollar.
Actually, someone replied yesterday and said he would sell it if I agreed to purchase it at the automatic appraisals price, here's the catch, he hadn't even got an appraisal yet so he wanted me to agree to whichever price this software spit out.
