I use the blog sized Chitika unit centered at the bottom of each of my product pages with a 160x600 YPN in place of the left side nav and have been pretty impressed. I get 3-5% CTR with $0.20-0.80 per click on Chitika. YPN's CTR is lower but per click is even higher. I have been getting close to a $10.00 ecpm on one site, which is a few times higher than with AdSense.
