...a good CRT monitor is still the way to go for graphics work and photography (as well as gaming). CRT monitors have faster refresh rates and finer calibration options for graphics work.
My son is a graphics professional, and, although LCD monitors are fast improving, he still uses a CRT for his work. He's also a gamer, and insists that a CRT monitor is superior to an LCD as there is less ghosting, etc.
Both he and I use the Viewsonic Professional Series PF790 monitor. This is probably one of the best CRT monitors around for handling professional graphics (Google its reviews).
This is a plug-and-play monitor, and it is both PC and Mac compatible. It's an older Viewsonic model, but it's still highly desirable. I found mine on eBay for about $100. Be warned, however, this monitor is HUGE, and it weighs 50 lbs. No small footprint here!
If you can still find one of these PF790 monitors, you can't go wrong, and you can use it until the LCD types catch up to the CRT's performance. It's a great economical choice with superior graphics management.
Just one other bit of info...
If you buy this monitor and have it shipped, make sure the shipper protects the screen by taping a piece of cardboard over it. The screen has an anti-glare coating which will scratch. Shipping via UPS should cost about $50 in the U.S.
