The Sony
F500R and its successor, the
F520 are widely considered to be among, if not the very, finest consumer CRT monitors ever produced.
Dell, HP, Compaq, and Gateway, that I know of, all offered rebadged versions of the F500 monitor among their premium product lines.
I have the F520 version, and love it. If you're looking for a CRT monitor and you can find one of these or one of its rebadged siblings, from a reputable source, go for it.
Possibly the ultimate Sony CRT monitor is the 24" widescreen (16:9 format)
FW900 - essentially an F500 on steroids.
