There is a lot more to a monitor than it's physical dimensions. The 27 inch display that you linked has a similar or lower resolution than most 23/24 inch displays and is a tn panel with limited viewing angle, color reproduction, and overall clarity. There are many good options for quality 24 inch (1920x1200) panels at reasonable prices but 27/30 inch panels at resolutions that make those inches worth having (2560x1600) are still quite pricy.
