dial up modems

[Douglas Pollard]

Been doing battle with Comcast I am their only customer at the very end 
of a line. They won't repair the line problems because one customer does 
not justify the cost.  I am going back to dial up and am wondering what 
type of dial up modem to get.  I believe there is a list of hardware one 
line someplace   . I have Googled for it without any luck.  Any help 
will be appreciated.                           Doug
