All I can say is I'm VERY happy with the 19" Viewsonic A90 I bought a couple weeks ago. It'll do 1600x1200, too. It was $350 with a $50 rebate at the local OfficeDepot, which made it the same price as the 19" KDS there (not including tax). I have a lot of respect for Viewsonic monitors, just from their reputation and the experiences of my friends.
The rebate, I think, is not exclusive to Office Deopt and available until the end of the year.
I was going to go with a 17" for my spiffy new G4/500 DP, but opted for the 19" instead, and I'm glad I did. (Unreal Tournament at 1024x768 in 32-bit color looks great :-)
Cheers,
