I'm to happy to help. I've been a cord cutter since around for gosh probably pushing 7 years or so now. I can perfectly afford it but I refuse to support cable tv price gauging.
Life time, NBC, History, PBS... free on Roku and Amazon fire. PBS requires an account now I think, free so far. On the news front pretty limited but CBS News 24/7 is one i go to during the rare moments I want to hear chatter about news. There are probably other free channels but for the most part I use Hulu and those listed. I use PLEX to access CBS because they're jerks and keep pimping their All Access crap. I won't pay that monthly fee for the two shows I watch.
Now TNT, SyFy FXNOW require a paid login. CW might be free... not sure don't watch those before or after cable cutting... those are the ones I just know off the top of my head.
