What's affordable price to you? If you want a "photographic" monitor, be ready to spend a minimum of $3000, otherwise a great monitor is the 24" Gateway model that now is selling for $475 ($650 last year) and doubles as a great Full High Definition (1080p) screen, so awesome for Blue-Ray.
This monitor swivels 90 degrees and allows you to work on portrait shots. Also includes a USB 2.0 Hub. It would have been my second monitor if I had not had to shed 3 times that amount to my dentist
I've been drooling over it for a year.
As for the PS color issue, frankly I'm tired of it. I tried everything and I can't correct it, even Windows FAX/Pic viewer shows better colors.
