I'll list a few thumb sites...
http://www.hairytaco.com/ - Teengodfathers site.. I really like this... the name, the design.. it looks like it will get bookmarkers and makes good $
http://www.ethnicpassion.com/ - more than just an average thumb tgp.
http://www.5000galleries.com/ - sort of a thumb site & multicat rolled into one.. some reason this design really stands out
http://www.vidsworld.com/ - simple clean design but good thumb quality and content
