one of the better sites for comparing service providers in your area is DSLReports iAs far as I know they are not associated with any service providers.
Have a second apartment in Washington, DC. Suspect that my online queries lead to sites backed by providers. Seeking for guidance on how to determine the absolute best rates by zip code. Main use is email through a Wi-Fi mobile device with no cellular contract...I did just acquire a Vision Wi-Fi TV.
Perhaps there are others similarly situated.
