I agree. They can be great for targetted traffic if you find the good ones (not easy). You have a picture and/or description... if the surfer likes what he sees, he clicks on it... and if you're honest, you can't get much more targetted than that.

The problem is finding the good ones. Best bet is to use niche specific ones and really concentrate on them The numbers may not be big, but they're looking for what you're offering. And, you're more likely to find some good ones that way, because a lot of times they are started by people who are really into that niche and got tired of all of crap. Be ready to jump through some hoops to join some of them, because of the ways they come up with to cut back on the cheating . I just spent a good part of the last month linking up a few niche sites, so I know it's not that easy to find them, but can be worth it.
