I second the Roku TVs. I have an Android TV in the living room and it aggravated me so much it now has a Roku plugged into it.
We recently purchased this 43" 4K TCL Roku TV for our bedroom and it is fantastic. Stick a thumb drive in it and you can pause and rewind live TV. It's only 220.00 on Amazon right now! Tempted to buy another for the RV.
