Re: Hmm, isn't that trivial to obtain?
"When I was looking two or three years back they were hard to find, I expect they're impossible to find today"
Just checked a local electronics chain's web site.
Found a 55", non smart, 4K (3840 x 2160) TV with 3 x HDMI, 1 x RF, 1 x USB, composite and component video inputs, optical digital audio out, and VESA mount compatibility for $500... about $700 less than a smart TV of identical size and similar specifications from the same manufacturer, with both on sale.
You could get a 75" smart TV for $1,500, if you thought you could quarantine it reliably, also on sale.
