Actually, Verizon has plans at around $6 and $12, plus taxes and fees. Very, very basic plans, but they would work to get DSL. So it pretty much is the same thing.
Verizon doesn't advertise those plans and will barely acknowledge they exist if you call them. Also it's the taxes and fees that make POTS expensive. The fees can be upwards of $10 a month. -- The Comcast Disney Avatar has been retired.
