The problem is that as new service packs and hotfixes come out, they tend
to cause regression in the security of the system... as do new applications
(such as, perhaps, a new proxy for a new protocol, or an anti-virus filter,
or whatever...).
You may well be competant to set up and configure an NT based firewall, and
maintain it, but in general it's much harder to secure an NT box than a UNIX
one, and much harder to ensure it stays secure, simply due to the dearth
of available information about what all those mystery files in %systemroot%
really do.

I didn't say it was cheap, I said that it's the first level that actually
has meaning in the context of a firewall.
