I'm intrested in making myself a logo like the one seen for Baseball teams, and I see alot in New York

Kind of like the text style used for

Baltimore Orioles
Atlanta Braves
Houston Astros
Milwaukee Brewers
Montreal Expos
San Diego Padres
( you can see all those logos on http://mlb.mlb.com/NASApp/mlb/mlb/te...team_index.jsp )

I was wondering if anyone had any advice on fonts to use etc.
