Has anyone recently done a comprehensive analysis of all the major charities to determine which organization(s) provide the best bang for your bucks in various categories etc. For instance, which charities have the lowest administrative costs relative to their total net assets? Which ones have the largest marketing and other overhead? Which ones have questionable histories/records? Which ones have liberal/conservative political ties? etc. you see what I mean.

According to a well-known biography, Warren Buffet did this and decided to set up his own charitable company and donate to it only. That is, he found no existing charitable organization which was run well nor (according to him) worth giving to.
