My speed growth over the years:
300 to 1200 baud Apple modem --> 24 baud Hayes modem --> 14.4 modem (don't remember the brand) --> 56k U.S. Robotics modem --> DSL line (can't remember the speed, but faster than the U.S. Robotics modem --> 2.5 MB cable modem --> 7.0 MB cable modem --> 10.0 MB cable modem --> 15.0 MB cable modem.
The highest they offer is 30 MB cable modem, but my pocket is not that deep.
