Hi. Thanks for the citation.
The updated link to the EST Extractor is now

but the one cited still works, buit may have problems with DNS

May I also suggest to give a look in general at, in particular
the CAP Assembler (interactive assembly of FastA sequences) & CompBlast
(DIY Blast service) should be fit to Dr. Ebbole's problem.
The Cap2 / Cap3 assembly programs are (were ?) public domain 
programs from X.Huang: The graphical
interface for NCBI Blast parsing is also public domain:

Best Wishes,
