I had this conversation last weekend with a friend that has a hotel right on the Gulf.
So tons of humidity, rain, and salt water air....that rusts everything.
The answer from him was to buy a TV knowing if it doesnt get stolen, it will last 4-5 years for him.
You are in Ohio, so I wouldnt expect same issues.
He buys $300-$400 sets on sale, he has a few around the hotel property, and feels fine at the amortized cost.
Maybe this is of help.
