I don't really trust those dental directories that send you to the highest bidder. I haven't had good experiences with them either. Thats why I was so happy to find Dr. Davidson, who was recomended to me by a friend. I figure the least I can do to pay back the good doctor for all his straight forward and honest advice, friendly office atmosphere, and most importantly successful treatment, is to give him a rave review on a dental guide like this.
