I’d monitor http://www.gotapex.com - they seem to be plugged into the Dell deals. Every so often (and frequently coinciding with a end of Dell’s financial quarters) there’ll be lots of sales with coupons and associated discounts. The monitors show up there on a regular basis.
All of these are 20" widescreen. Word of warning though; 20" widescreens are less tall then 19" 4:3 ratio moniters. You get more viewing area overall, the scale of everything is smaller. Just smaller over a wider area :). Text, ect, on the web is smaller at the same resolutions.
I have the Viewsonic 2025wm and it’s nice. Runs 350-ish right now shipped. Has some DVI issues sometimes - i had to ship mine back and get another.
The Dell 2007WFP has component out, and is Vista ready. Some say it had banding but that’s been corrected; other forum tards say they change the panel out without changing the name of the moniter. Whatever.
The NEC 20WMGX2 is supposedly the best moniter out there right now; but it runs 650$US+, at which point you could get a larger Dell moniter. Has some kind of glossy coating that some hate and some love. Supposedly the best for gaming right now.
Spotted at Hot Deals: Samsung 930B for $219 with free shipping, plus $30 rebate. Looks like a pretty mediocre monitor, but its price just dropped $100, so it may make a decent bargain. Also, a Viewsonic VX922 for $300 plus shipping, with a $100 rebate. The VX922 looks like a good budget choice for gaming, thanks to its low response time. These are both 19" 1280x1024 monitors: if you want bigger, widescreen, and/or higher res, you’ll have to look elsewhere.
