You have to do it in this fashion to make $ wise. If you fully bundle your current cable package and have a higher package then cutting the cord all the way will make a good option for you.
I went with ooma for my land line. $5 flat fee a month, after you buy the base. It works pretty darn well.
The only option I kept with Charter is my internet $60 a month.
Last year, I put up a high grade over the air antenna $80. I get CBS, ABC, CW, MeTv,MOVIES, Fox,NBC and 4 different PBS stations which includes MT govt channel.
With Roku, I bought slingTV. That is $20 per month and sports package makes it $25. As GrizGuy said with ESPN, there is the WatchEspn (espn3) app, which has converted to Sling. Honestly, you get a ton of pretty decent sport options from it. Plus with Sling, I get ESPN, 2,news,U, SEC and theur GamePlan channel. Game plan is like an NFL Redzone for college weekends.
Last month on Roku, I subscribed to the Smithsonian Earth channel for 3.99 a month as the kids liked it. This month, I dropped that channel (all from my login account, no customer service needed) as the kids weren't watching it as much.
Roku has so many pay and free options, you can always swap in and out. It's still grassroots in many ways but TV the way I see it should be as ala carte.
Before I was paying almost $200 a month for a bundle package and no movies channels. I like Sling as its basically the same channels I used to watch anyway. Because I subscribe to sling, which includes Disney, I am able to get a semi free Disney Jr app for my son to also watch on Roku.
In addition, once I started looking around on YouTube, there are so many different types of cartoons options. Plus with Roku offers some transformers and gi Joe 80's etc cartoons, the kids don't notice a difference.
I find there is even more documentary and learning type channels on Roku that it satisfies.
It takes a bit to overcome and learn what's out there. But there are endless options both at a small fee or free, its pretty amazing.
Plus, I'm still way more satisfied that I at least cut my bill in half and it shows in my savings acct.
Sling give you around 14 channels plus some on demand options for each, its pretty breakthrough, I think and I joined only one month after it launched (Feb '14)
What Hola is talking about is that MNF had some high demand early in that the servers couldn't keep up. They have up graded and since, I haven't had a problem. The downside to Sling is one pay one use. In other words, I have 2 Roku boxes, one for the bedroom and one for the living room. If I'm watching Sling in the front room, my wife can't watch it in the bedroom without kicking me off. It also comes with a mobile app, so if the kids have the TV on something else, I watch a game on my phone.
