The question only you can answer is how good is "good"-academically. While top DI baseball programs (Texas, Miami, ASU etc) are exclusive in skilled-player recruitment, many of the academically exclusive DIII schools need 1350-1500 SATS scores, and maintain 20-25% acceptance rates from an already self-selected set of top students.
As something I'm experienced with (DIII liberal arts schools), I will offer that, from among U.S. News & World Reports 2006 top 25 liberal arts schools, six have what could be considered "good" baseball programs.
For this post I've referenced "good programs" as those with current, consecutive winning seasons and at least one recent post-season appearance. Issues like "the coach is a great guy" can't be compared.
NOTES: Several of the top 25 liberal arts schools are essentially womens colleges not offering baseball and one school, Colgate, is in the DI Patriot League.
All the schools listed below are in the East. The U.S. News academic rankings are listed after each school name.
Williams (1)
Amherst (2)
Bowdoin (6)
Haverford (8)
Washington and Lee (14)
Trinity (25)
Obviously, other academically elite DIII schools, Johns Hopkins for example, have "good" programs, they simply aren't listed among liberal arts schools.
good luck
