I've been very happy with fidonet, and you'll find Jon Morby is active on this list. Customer service is very responsive any time day or night.
I can usually max out my fttc line (36/5 M) any time day and night, so there's no slowdowns during peak times. As a result get excellent Netflix or iPlayer, virtually never see buffering or H.A.S. reduce the quality Native ipv6, static v4, uncapped, unfiltered, unshaped. Price isn't too bad for 200 GB a month.
