My dad was at the end of the line with DSL in rural north FL. Similar prices for a few MBps. Finally switched over to ATT unlimited cell service, getting 40 MBps with some kind of deal on direct tv. So much better. He has dual directional antennas points them at various towers trying to get best signal.
Rural cellular is the future. Currently posting this from the mountains of NC on Exceed satellite as there is no cell service at this campground...
