There are two issues here, which are getting mixed up:Input Lag
is the delay between when a image is sent to the TV and when you see it on the screen. Manufacturers do not publish specs for this; at best, they claim to have a "game mode" that reduces this delay at the expense of some image quality. Typical values range from near-zero to over 100ms (1/10th of a second.) This is a critical issue for PC use and some types of gaming. Too much lag can cause a "drunken" feel, and makes timing-critical moves more difficult. As was mentioned previously, the Input Lag thread
has tons of details about what it is, what models are most affected, etc.Response Time
is the time it takes for a pixel to change from one brightness to another. This is partly responsible for the "blurring" effect. This is the spec that manufacturers do publish, and is usually between 2 and 8ms. Unfortunately, there are different methods for measuring it, and other factors involved with blurring, so it doesn't tell you much about real-world performance.
There's no perfect solution, as improving one usually impacts the other. It's a compromise: Lag, Blur, Quality -- pick any two.
And for what it's worth, I bought a 37LH20-UA from Best Buy in January, which has an IPS panel in it. Low lag, reasonably low blur, with the tradeoff of rather poor black levels. There's nothing "awesome" about it, but it's great for XBox 360 gaming, which is really only 720p anyway.
