[Wlug] Internet service for newbies

This is in regards to the install fest that will be happening Saturday at the Worcester Computer Coop. These machines will be given to people with little computer experience / money. All they need for an Internet service is a very simple dial up. Has anyone tried Net zero for Lindows(linspire) and got it running under Linux? If not can someone recommend a good ISP. The cheaper the better. Thanks Patrick
