We used OpenX for a few months, but switched to Google after our host repeatedly shut us down for utilizing over 80% of the CPU. It was traced to an OpenX script. This bug was verified by OpenX. I'm not sure if they fixed it or not. I'm glad most of you have had good experiences with them, but we had more problems than it was worth.
