60 hz vs. 120 hz lcd tv's?

If you watching a lot of sports I think 120Hz worth it.This technology doubles the frame rate from 60 to 120 frames per second without repeating the same image to make more frames that can reduce blur. http://www.amazon.com/gp/redirect.html?ie=UTF8&location=http%3A%2F%2Fwww.amazon.com%2Fs%3Fie%3DUTF8%26rs%3D979929011%26ref%255F%3Dsr%255Fnr%255Fp%255Fn%255Fsize%255Fbrowse-bin%255F3%26bbn%3D979929011%26qid%3D1242344511%26rnid%3D1232878011%26rh%3Dn%253A172282%252Cn%253A%2521493964%252Cn%253A1266092011%252Cn%253A172659%252Cn%253A979929011%252Cp%255Fn%255Ffeature%255Fthree%255Fbrowse-bin%253A724227011%252Cp%255Fn%255Fsize%255Fbrowse-bin%253A1232882011&tag=computer0bd-20&linkCode=ur2&camp=1789&creative=390957

i would say yes. but it also depends on what your watching. if your watching a regular movie then 120 hz makes the motion look fake, and unnatural(although some people tend to like it better) but if your watching something like sports or a nature show(like something on discovery) then 120 hz makes it look ALOT better, the motions are alot less blurred and makes it seem like your actually there. so overall i would say its very worth the price difference!

unless your tv is bigger then 40" there will be no difference as tv is only broadcast at 50 or 60hz (depending on country) and we only need around 35hz for our eyes to see something as smooth video there is realy no point, but on larger screens the higher refresh rate can benitit if you sit close to the screen, although if you are sitting at the recommended 2.5x the screen size away from the tv (to reduce eye strain) almost any tv at 60hz you will not notice a difference to one at 120hz
