Greece???

not sure if this is where to ask, but... I am traveling to Greece for about a month and I need internet access. I will be on an island so DSL is out, but I figure I can use dial-up as I will have the telephone connection, but I don't know any ISP's. I was wondering does anyone know of an ISP in the United States that extends its service to Greece, or does anyone know of any ISP's in Greece that I can sign up with, without too much difficulty or price???

thanks-
