Firewall opinions wanted please

You're not going out on a limb; you're absolutely right, and I've been
saying that for years. I'll quote myself:

   Although firewalls are a useful part of a network security
   program, they are not a panacea. When managed properly, they
   are useful, but they will not do everything. If
   firewalls are used improperly, the only thing they buy you
   is a false sense of security.

Beyond that, different security policies have a much greater impact
than different brands or types of firewalls.
