Even in this modern Internet age, a good Internet service provider is hard to come by. In most areas, service is only available from a select few with a single provider dominating the market. There are hundreds of small companies out there offering "unlimited" bandwidth and advertising high-speed connections only to fail at delivering on their promise.

This leaves you with the option of forking over large sums of money to receive reasonably stable and consistent service or having to clench your teeth as your connection is regularly interrupted in order to save a few bucks.
