When I ordered combination high-speed and cable TV from Comcast in August, I asked for bsaic TV only.
The weekend before the appointment I received a call suggesting I "upgrade" to digital now: "In a few months all Comcast television will be digital. If you get digital now, you'll save on paying a second installation fee at that time."
Getting back to la3's quandry - isn't cable faster than DSL? I admit I'm hooked on high-speed. It's one area that off-the-table in terms of budget reductions.
