Thanx Jim for the honest appraisal. I was starting to think there wasn't a dot-commer in the house . You are right about the hyphen-- while this is the most popular spelling of the word most people would still type in dotcommer.com rather than dot-commer.com, so I won't get my share of the traffic. Still I'm holding out for $99 on my price. Some commer with a big ego will bite. May bite. Hopefully will bite.
Verbalization, memorability (and hence referrability) and vanity are the main factors against hyphenated domains.
The value discrepency is backed up by large volumes of sales data.
The thing with search engine domains is they can create them for reg fee that will pull well whereas its unlikely they can create a vanity domain for reg fee.
