If you're looking for Spain,
http://ww.sponsorhispano.com
Dialers and creditcards with good niche sites.
They are part of the same network as eurodialer
but pay more for Spanish traffic.
http://webmaster.nocreditcard.com is great for globalreach
or there's a company in Canada
http://www.sexodinero.com
That has dialers and cc through the same link.
Spanish traffic does not do well with CC only 5% of your sales will come from a CC.
