You should look on alt.internet.access-wanted (i think that is the newsgroup).
Most major cities and suburbs have a number of options at this point.  In
Seattle, Pittsburgh and Philadelphia (the three cities that I've lived in
since the beginning of the summer) there seem to be places that will offer
$20/month for 3 to unlimited hours per day (depending on the provider) for
SLIP or PPP.
