We don't recommend Verisign and are migrating away from them for two reasons:
1. The SiteFinder service fiasco.
2. Their libpfpro.so library is statically linked against an old version of OpenSSL. It causes AOLserver to coredump (on our site) at least once a week, if not more often. It took us months to get an official answer out of their support organization, and in the end the answer was "we're not going to fix it".
