Different names pays good at different places. Domainsponsor and sedo seems to be the most popular for names converting well into clicks, Domainhop for names converting less and Fabulous for gambling related names.
If you have a good amount of US and European traffic then it's Domainsponsor...Nobody beats them in terms of payouts I average $35CPM with them and upto $100CPM on a few domains.
For Asian traffic, Sedo pays pretty well.
For low CTR traffic, Domainhop does well provided you meet their minimum RPM of $2
