Ugh...both of those names make my asshole pucker up. I have Spooktrum here...They bought Insight years ago. It's ok, 600mbps for $40 is a decent enough price.
Used to have WOW, they bought the AmeriCast system from Ameritech / Ohio Bell years ago. I've heard the system was patched together with love, tape, and the know-how of the WOW people, and Breezeline got the pig in a poke treatment. AT&T fiber is the other local, but I don't like the way they do the NATless stuff on consumer fiber.
