Here are some links I recommend. The St. James Music Press publishes collections of anthems and other church music using the same format/pricing scheme as Church Music Services, Inc.

The University Choir, directed by Dr. Robert Delcamp of The University of the South, has several excellent compact disks.

I'll be updating the links page regularly.
