Also, I have to say that because you are keeping the same 20" 1680x1050 resolution perceptive screen size might increase, but picture quality not. 22" panels may offer the best economical balance between the price and features but they can't match the quality of best 20" monitors - yet.
If your budget is tight and your choice is between 20" mid/low range (like LG L204WT or VX2025WM) ... I don't see any particular reason why not opt for the 22" range.
