You mean cheap as in the slang for worthless?

Security is a *process* not a product.
See the Orange book criteria.

Huh? I don't care who my vendor is. I am paranoid enough to patch my
box(en) and keep them patched. Extremely well patched. My box is 24 x 7
onlne and has no firewall. However, breaking into it will require a
0 day. A service that is not running cannot be broken into.
(For a single box a packet filtering firewall does not make sense. The
only services exposed to the net are those that I want public, all the
rest run on unix sockets/localhost only. If the box is broken into,
reinstall time, and the damage done is 100% anyway. No, I do not see how
a packet filter can protect against an application layer exploit for a
Net exposed application. You need an application level proxy for that.).

You mean defaults? Who cares about defaults? Not even the OpenBSD
people care about defaults, even when they claim that the default
install is secure.

A secured distro is a good starting point, in that it reduces the amount
of work to be done for securing a box.
However, security is only as good as the admin. Finally, stay patched.

The correct way of obtaining security in defense in depth, proper use of
cryptography, not running vulnerable services and running secure ones
only.

Net -> Packet filter (get rid of a lot of crap so that the proxy has
less work to do) -> proxy (clean up the input, if possible) ->
application (which trusts no external input and has no known exploits).
