Yesterday we shelled out 1720 NIS ($431 by today's rate) on a new 22" wide-screen LCD monitor for our PC - LG L226WTQ.

Another thing I really wanted it for is double-window work, such as programming (I usually have two editor windows tiled vertically, or one editor window and one with documentation / web for examples and googling). This monitor can easily play the role of a dual-monitor setup. Here, judge by yourself:
