When it comes to CPC, no one can rival AdSense. Clicksor is total crap from what I know, and anyone associated with them I assume would also be not up to par. Go with decent advertisers like Adsense, PulsePoint, ValuClick, etc. Try your hand with BSA or Rubicon if you have much more traffic.
Sadly, my account was randomly disabled by Adsense shortly after the event named in the article. I'm not sure if Google didn't like the ads Xtargeting was using, someone spammed click my site, or something else. Since Google doesn't tell you what you did wrong your account goes down and there is nothing you can do about it. I'll look into the other sites you listed. Thanks for the suggestions!
