Condition and completeness is everything and that one looks exceptional.
ten or more years ago one in that condition with all the antenna parts could bring $200 or more.
This much poorer condition one recently went for $167, probably because it was showing a raster.:

Knowing for certain the CRT was good would be a big factor in what I'd pay.
Outside of eBay I'd probably offer $125-$150 if I really wanted it.
