AdBrite - anyone using it with success?

used it briefly in the past, found it was mostly junk traffic that didn't convert (mostly). If you can get your sums right on the ad buy vs signup rate though it could work...although I didn't stick around long enough to try.

we've been running an ad on one of their sites for almost 12 months...been getting great returns from the get go...the problem is finding other sites that look like they have the same potential.
