Should I buy another flat screen now while they are still relatively cheap?

Good question. I have wondered the same thing. I decided to wait. Since even if the cost went up 50% they would still cost less than most of my audio cables. 

After years of buying by cost point, my last 78" OLED and 65" LED for the bedroom have been top of the line Sony. Both were replaced under warranty when they failed in different ways. I had done my research and knew they were the most reliable at the time, so I was unlucky. They have very high video quality and the Bravia warrantee is better than the lower cost ones. When these need replacing I will replace with Sony.  

Sony , Panasonic and LG all use the same panel from LG. It seems the Sony's many times have software issues according to the Costco reviews which is the best place to buy , better prices , service and warranty by far. For me the brilliance of the QLED Samsung is far superior to the other brands and reliability is excellent. Last year and most others Samsung sells more TV's than LG and Sony combined. Can't see buying a set you don't need and as others pointed out they keep going down and also technology keeps improving. I don't buy into the tariff stuff.

Prices will rise and shelves will be bare.

Your current TV is old enough to fail, so, buying now is probably wise. And I should also buy a tv while there is still a good selection! Thanks for mentioning it.

Don't forget to buy your five pencils!!!!

...and 3 dolls if that applies to you.

@bigtwin  entry is correct and accurate.  I have a Sony LED that I bought 16 years ago. That TV owes me nothing. I use it approximately 15 hours a week , sometimes more. Never fails me ( of course tomorrow it probably will crap out). 

I dread looking for another screen 16 years later.

Are you really @jerry123 and @hifiworld2024 ?

That is fascinating.

To the OP. Your concerns are valid. It doesn't take a rocket scientist to figure out the US is not getting shipping containers at the ports. If somebody knows where thousands of factories are being built in the US right now... please tell us all.
