I usually can get at least 49.2 on the connection. Sometimes I can get 50.6 although you'd never know the difference.
I pay $15.95/month.
You might check Netzero.com. Their dialup is under 10 bucks but I don't know anything about their reliability, speed, etc.
Thanks for the recommendations. I just got the renewal notice for my current ISP, and I definitely need a change, as their customer service is seriously lacking.
