As a coach and tournament director, finding easy to use bracket software that was affordable and kept accurate team score was difficult to impossible. That is why I wrote my own program in Excel and had it tested against the 2009 NCAA division II and division I finals. I have taken further steps to make it publicly available athttp://excelbracket.freewebpage.org/
If anyone needs to run an efficient tournament with minimal setup and up to date team scores, please refer them to this site. If there is a need for brackets larger than 16 man, I can accomodate requests.
