On my GE shelf, I have three GE Porta-Colors and a Samsung-built, GE 9" set, probably built in the mid-80's. While my Porta-Colors are in great shape, they still don't have the picture quality of the 9" GE set.
I guess, I get spoiled watching a really good color picture and I'm a little hard to please.
I, personally would rather watch a really good B/W set, than a boarderline color picture.
