I'm flattered when people who have a great need to prove me wrong resort
to spelling and grammar issues. Even when they're wrong. lol

This is just my observation, but I think the reason is because the
manufacturing costs of a DSL modem are lower than a Cable modem. This
is because the CM requires a lot more shielding to prevent
interference with nearby radios. DSL modems don't seem to have this
shielding (and radiate a lot of trash), and so more of the budget can
be spent on add-ons like NAT gateways. However, when my folks got DSL,
the first modem they got from Verizon was not a gateway. I'm not sure
if they were charged more for the gateway or not, but I know they sent
it out without any question.

Comcast has a "home networking option" available that includes a NAT
gateway equiped CM (installed and supported by comcast), but it is a
somewhat high priced option, when you consider the price of a seperate
NAT router/gateway.

Interesting, thanks for the responses everyone!

The main cost difference is probably due to the tuner itself. It's bulky
and needs all that sheilding since you are working with frequencies
approaching 1GHz. I think DSL only goes to a few MHz.
