I have always liked those little Emersons especially because of the included radio. That woud have been a perfect bedroom TV back in the day.

The aluminized CRT's always lasted longer.
Some people have the popular misconception that an aluminized CRT didn't use an ion trap. The aluminized CRT's had a lot more brightness and contrast and didn't have to be maxed out in a brightly lit area.
