Can you get cheaper hosting? Probably. Can you get better service and value for your money? I seriously doubt it. My sites are in good hands at SpeedHost.

An Example

You decide to join SpeedHost.Com on January, 2000; signing up for the SpeedWeb ($20.00). After experiencing this great service you decide to bring your best friend in. Your friend joins in February, 2000, also signing for the SpeedWeb. Your next credit card charge will be for $17.00. In March you decide to bring yet another friend into the system and open up another site for yourself (both SpeedWebs). The next credit card bill in your primary account will then be for $11.00! You will continue to save forever! (unless you or your friends decide to leave SpeedHost.Com)
