All of the 22" panels in the $300-$400 price range perform very nearly the same. They all use 5ms TN panels. So, read just about any 22" monitor review to see what you're buying into.
In my opinion, the 22" panels are a good value. The TN technology is not very good for viewing angles, color accuracy or black levels, but the size and low price make these monitors tempting for many.
