Input lag on Samsung LCDs

I'm in the market for a 2010 Sammy lcd, and as I'm sure many of you use Samsung lcds, I'm curious to see what you all think of the input lag? Noticeable? Bearable?

i just got a 40` 240hz 1080 plnb750 and its great. no lag at all. infact my kill/death ratio on mw2 has gotten alot better since i got my new tv. i got it set to vivid and default settings and 240 hz on clear. can see people on the other side of the map peeping out windows even on boards with snow and ran or dust.

its by far the best tv i ever seen or played games on. i got it on sale for 1098. it should drop back down to that or lower in a few months when the 2010 models come out. if you see it anywhere near 1 k again stag that baby!!!
