I bought one of these a few days ago when my 4 year old 17" Samsung 700s died. I just got finished building a new system and didn't have a lot of money so I picked up one of these at Walmart because they have a 90 return policy. I figured I could use the KDS for three months while saving up to buy a better monitor then return it.
This monitor has surpassed my expectations for such a cheap unit. I was able to set the geometry so that everything is square and the color looks pretty good. Text is sharp enough by my standards. My only quibble is that with a completely white screen the right center portion of the screen is slightly warmer than the rest. It's only noticable with a white background and is minor.
BTW I run it at 1280 X 960 at 85Hz with a Geforce 2 MX, color temp at 6500K, calibrated using the Adobe gamma utility that comes with Photoshop Elements.
