I used to have Sling. It was okay. When I started it was 30 bucks a month. As the price started going up, I started to look at what I really watched with it.
I can get what I really watched on Sling by paying 4.99-7.99 a month for certain packets with content I watched on Sling. I found this way cheaper than Sling.
I have done great without it.
I figure if I stop subscribing to several things on Roku that I rarely use anyway, I will make up most of the cost of Sling, if we decide to get it.
