CCleaner for Mac

Got excited to see that the famous Crap Cleaner which is and has been forever in my Windows toolkit made the trip to the other side. As i morph more and more into an avid mac user, this makes me happy. HAd some alternatives, some even better, but also a bit dangerous in terms of tweaking registry entries (especially since from my experience things are far more complicated under mac osx than win), CCLEANER came through.
