I have them all parkes on sedo, themetatrap.com had 10 unique in under 4 hours without referrals and besteasydeal.com has a good history and lots of links. Northsupplyinc.com has steady traffic.
Ana-max.com was rated tier 3 by some appraisal guy for about 3k but that sounds too out there
Listtransit.com sucks
