I picked up the Samsung 151s for a system I'm building (mainly internet, word processing use for my Aunt) because it was the #1 Editor Choice at CNET & after reading the many positive user testimonials. Pretty slick looking LCD! The viewing angle is excellent but for First Person shooters, I rate it just 'okay'. CRTs are still the best, but I was still able to log in 2hrs of CS without much complaint My response time is 30ms so ghosting is not really that pronounced with this monitor, but it still has that gritty look to it when you're running around (Might be the onboard 8mb 845GL graphics I'm using) But for 2D games I it will be just fine.
Overall it's a great monitor for everyday use. After a couple of days of "testing it out for my Aunt " I have to say. I like it. My eyes don't feel any more straind when using LCD compared to CRT (I use NEC FE700+). And it stays very cool when running too -unlike my hot running NEC. And when you turn on the monitor the picture is instant, no need waiting for it to warm up.
Problem is I never see any deals going on for this one.
Update: Oh yeah, I also have one dead pixel in the lower right quandrant. Funny thing, when it arrived and I hooked it up it didn't have any! Only after like 2 days of use then it appears
