here's mine (just for S&G):
Teraton cablemodem (provided by cox free of charge)
connected to 4 port hub (port 1)...
primary firewall (linux MDK 2.4 kernel) on port 2 using iptables
secondary firewall (openbsd 3.7 using pf) on port 3 of hub
both firewalls are connected on their internal interfaces to a primary switch
for the house (one on 192.168.16.1 and the other on .254 same subnet).
I have been migrating my stuff over to openBSD because of its higher
reliability and better firewall capabilities (there are just some things I
cannot do with iptables).
both firewalls have their own outside IP addresses.
as for connectivity issues: downtime this year: 2 hours total
throughput (on the best sites) > 400 KB/sec down and >70 KB/sec up with a
latency on saturation of 10 ms.
now, I have been a cox customer for just more than 6 years without a major
outage and I have bundled telco and catv (digital) with these folks. so far,
they have been far superior to QWEST in every way (I had significant troubles
with qwest as far as service and other issues went).

craig, this statement is only true at tier 1. I have spoken with many tier 2+
individuals who are willing to do "independent analysis" on the fly with
little or no difficulty. hell, in 3 of 4 cases, the person on the other end
of the line is also a linux user/admin (and in one case I was talking with an
NOC admin who was an old unix man). now, there may be problems with the
original posters location (such as long runs of cable between amps, or old
buried cable that needs to be changed out) or simply a bad luck of the draw
on cablemodem devices. again, this is just speculation on my part.
IMHO, cox is still better for a lot of ways, though their policy of blocking
specified ports for outbound access does leave something to be desire (just
about every major "broadbad" isp does this these days to "secure their
networks against problems").
