Does it have to be 19"?
Firstly, if your not that desperate, SED technology is looming, I just read about it and it sounds like something great at last. its basically all the size, weight, etc. gains of TFT, but using CRT technology which means you get no ghosting, screen burn, real black, etc.
Secondly, if you've not owned an lcd, look at my ranting here:

I should note i own and like TFTs for the gains, although it would be wrong for me to say that they don't have the flaws they do.
Thirdly, i'm a big fan of Dell's work, they offer great value, lots and lots of core functions, decent performance and... well they look good. i have a DELL 2001fp (20") and its getting on now, there are better, newer dell monitors out. There's some neat widescreen onces. Large native resolution which maybe bad if you skimp on graphics cards and are an active gamer, other wise its a huge bonus.
As far as 17" go, I believe illyama are still best, however they tend not to go into the bigger monitor markets.
