Although a US site, paying in dollars, this affiliate network offers probably the highest payouts anywhere for pay per lead programs. Most are geographically targeted and particularly suited to sites with a US bias, especially for visitors interested in completing surveys and taking part in sweepstakes or claiming freebies. What makes this one particularly rewarding is that any visitors that don't meet the geographical criteria don't just get rejected, but are diverted to other offers, at least some of which will be relevant to their country.
