I am waiting myself  for this one  from Viewsonic (22 inches model) but i have read lots good review for Samsung 226Bw

Attention : following commercial description but seems interesting for trhe gamut and screen control

ViewSonic's new 19-inch VP950b and 22-inch VP2250wb take professional-grade LCDs to a whole new level with OptiColor™ NTSC color gamuts, enhanced PerfectSuite™ Plus screen control software and Dynamic Contrast Ratios as high as 3000:1 (typ). These displays are ideal for graphics production, film editing and CAD/CAM design in which precise color rendition and crisp images are vital. They are also excellent choices for financial planning, trading floors and other applications where sharp text, clear spreadsheets and crisp graphics are important.
