Max and min screen sizes for early 80s TV's

[liammc00]

For a while I have been working on story that takes place in the early 80s, 82 to be exact and in this story/book I'm trying to keep things as accurate as possible for the time poried. So what max and min screen sizes for projection and direct view sets. I'm going to have the character buy a RCA XL 100 19" nob tuned set and would $359 be realistic or is it to high for the time.

For anyone that is interested the story takes place in the 80s and is about an evil doctor ho wants to create the ultimate soldier but ends up crateing human mutant fox who will ultimately stop the evil doctor in his tracks.

The story still has a long way to go hopefully I get it finished.
