You might not believe that some people are still using dial-up, but they are. In fact, the number of people using some version of dial-up internet still outnumbers those of us using broadband and high-speed. This is due to any number of reasons, but often because the users are away from urban areas. Copper.net offers internet service throughout America and parts of Canada.
Monthly access begins at just over $8.00, but that is not just "dial-up." Copper.net offers premium services, and does not outsource their helpdesk.
Further, they are accredited with the BBB and you can learn everything you want to know about their company from their website. While Copper.net focuses on dial-up services, they also offer dsl in many areas. Just fill-out the information page to determine whether or not DSL is available where you live.
