I haven't read all the other replies, but I hate the directories. It's like many have said, they are good for $0 comp checks. We are signed up with AppraiserUSA, Appraisers.com, and AppraiserGuide (which may have a different name now). Those are the only three that I've ever seen ANY sort of return from and even then, jobs are few and far between even with those three. We used to be signed up with several others as well but they were literally just good ways of throwing away our money with no benefit and no way to figure out if it was a benefit. Especially when so many people, when asked, "How did you hear about us?" simply respond, "The internet."
Service Magic used to get us the occasional benefit, but they can be costly too. Their direct lead program, which seemed the best, would also annoy our clients. They gave us a direct number that I'm sure was not only confusing in terms of figuring out which number WAS really ours but also they would introduce themselves as company reps and answer the phone as if they were sitting in our office. People would spend a good time giving them their information only to be transferred to us and have to do it all over again.
