I cut the cord nearly ten years ago running just DVDs, and regular TV thru an RCA converter box. Limited but no additional costs. The last four years has been a Roku box with the converter. The Roku running Netflix and the channels on the Roku list is ok.

I only pay for my existing mid-range WIFI which I'd run even if I didn't have the Roku so no additional cost beyond the Netflix script. May add Hulu later for more variety. Still very cheap compared to cable!
