Since the flat screens exist, all CRT are old now and will become rare in the future.
Sony is a good brand in the measur where you keep it in a working condition..Samething for Panasonic...Magnavox where very good back in the days but now I don't know...Dell for a computer, no problems I had and I have a Dell ...but for a Dell monitor, i can't say
someone else will be better than me for you.
