Here in the Seattle area, $20 or so a month is pretty normal(there are some
for as low as $15 if you pay several months in advance). And in many cases
that's with NO hourly charge. In the other cases, the monthly fee covers a
generous amount of online time (like 20 or more hours per month) with
reasonable rates beyond the basic (I know of one that has $1 per hour after
the first 20 hours, and no extra charge for SLIP).
