I had cable with faster internet speed and limited basic TV channels, this package being $3 more than just having the internet.
But, last month, I canceled the limited basic TV and took the internet speed down one notch, and, as I had anticipated, we do not notice a difference in the internet speed at all. So, I cut $20 off our monthly bill. I already save as we do not pay cable modem rental, I bought one a couple years ago. It is much cheaper to buy our own, they are a little expensive, but at even $5/month rental fee, it is paid off in a year and then it is just savings.
We do not do gaming online, just movie streaming and regular communication stuff and almost never upload. So, the medium speed is working just fine even when 2 computers are streaming movies
