Best ROI not counting AdWords and Overture

Who's got it?

Any takers? :)

Which PPC service, aside from AdWords and Overture, has offered you the best ROI on your advertising dollars?

Business.com: Good quality traffic, but can be expensive.

IndustryBrains: Very expensive, but the traffic quality is good.

Superpages.com: Decent traffic, reasonable cost.

Sometimes niche search engines can work well depending on your niche, but you will have to expreriment.

I second Business.com, but I can't say the same for Superpages.com - so far the results have been less than ok.

I've had good success with Business.Com as well. The Lycos AdBuyer PPC program has also converted well for us...I just wish there was more volume.

I would be interested to know of any business to consumer driven CPCs worked as well? What niche CPC worked for you?
