I've never heard anyone say that they regretted being a Boy Scout--not even Mr Munchkin, who quit his troop because the guys there would say virulently racist and homophobic things, and it appeared to be getting worse. His predecessor, however, was an Eagle Scout--he wasn't the nicest guy, essentially he was a jerk, but the Eagle Scout thing was the best thing he had done during the time that I knew him.
As far as money, it depends on the troop. Boy Scouts as a whole tended to be a lot lower maintentance than the Girl Scouts.
