ClustalW works very well. I used version 1.6 to align 60 rRNA sequences
(~1500 bp apiece) and it worked well. I did run into a problem in exceeding
the maximum length, but I believe Des Higgins posted recently that the newer
version (1.7) has no maximum limit except for available memory. A version
for Windows and Mac also exists, called ClustalX, and also works very well.
Versions of Clustal are found at the IUBIO Archive and in the Biocatalog at

I didn't see the original post for this, but if you are running
on a Unix workstation, you can also try AMPS. See our ftp/web site
