Pls Help! Good 20" LCD Display?

Hi, I'm new here. Pls let me know if this has been discussed recently
(most recent is about 12 mo. ago?)

I'm also new to LCDs. I am researching 20" (or that size range) LCD
displays for my MDD G4 tower. For years I've used a sweet 19" (18"
viewable) Hitachi RasterOps MC7515 that has amazing resolution and
color, but I'd love a smaller footprint plus I've been staring
at/getting irradiated by CRTs for 15 years. It's time to make the
switch.

1. An ad agency pal likes his 23" ACD, but I probably don't need more
than 21" max.

2. My budget is $800. I know this is a tall order but I can go a bit
smaller in viewable size if I have to.

3. Applications: text, graphics, photography, everything. I want great
resolution and color but I don't need to do color proofing (as in ad
agency work) - the RasterOps is still good for that.

4. Are dead pixels ever a concern? I've heard you may never notice them
but have to live with them nevertheless.

SO... what do you like? Apple? LaCie? ViewSonic? Model names and
numbers and prices would be a huge help (crushing work deadlines).
Thank you very much in advance - I'm new to LCDs so am unsure of the
performance parameters and issues I should be aware of, though I do
know about viewing angle issues.

In case it matters my system specs are: Dual-boot MDD G4 Tower,
1.25Mhz, 1.25 gigs physical RAM, 64 megs VRAM. Apple System Profiler
has this to say about the video card:

SLOT-1 (AGP)

Thanks very much! - Roger
