My brother says we would be able to network the computers, so we'll have to look for an ISP that supports this.
Personally I'd like to go to AOL broadband (from AOL dial up which I'm running at the moment) as that way I can keep my current email address and Buddy List etc...
Just seearched and found here:

that you can network AOL broadband, and even dial-up apparently now as well!
