The companies that are hosting for $2.99/mo might have a lot of customers, but their profit margins have to be next to nothing. I think it all boils down to quantity vs. quality. Sure, these $2.99 companys may have several thousand clients, but they probably have a lot of unhappy clients that leave shortly after signing up. They just depend on their low prices to bring in 'replacement' business. But the companys with higher prices will work harder for the client because there is more at stake.
