i think its not justified to pay the extra $$ for sIPS panel.. then new TN panels can give almost the same performance at a really low cost. go for either a dell or viewsonic.
I personally have a 22" samsung sync master, ------ing awesome so far. my second choice would have been an acer.
19": Samsung SyncMaster 971P, 1280x1024 (5:4) little more than 250 but it is a great monitor for photo editing (high contrast, accurate color/gamma curve, sRGB gamut) anandtech.com forums have a great list of computer monitors for varying purposes. check it out
