creating a DMZ -- seeking firewall advice

[Ryan Byrd]

so our small business is becoming a medium-sized business and we are
planning on switching from a bunch of servers running iptables to a
more enterprise layout with a couple of hardware firewalls creating a
DMZ for our webservers.

Any advice? I head that Cisco PIX firewalls are industry standard for
this type of thing. Anyone have any experience with those? Is there a
less expensive but equally as robust firewall?

ideas?
