I don't think there are any "good" places to list domains if you want good prices for them.
ebay has the traffic volume if you're happy with low reseller prices
end users are most likekly to come to you via the whois or your page contents rather than discovering listing sites. Or you can contact them yourself and see if you can drum up trade that way.
Thanks for the input "safe". I agree with your remarks. Some of the better domain sale that I have had, have been through individual contact via the whois search.
