Yeah. I'm not sure I have a lot of faith in a guy clicking the Human reaction test
So far every Leo Bodnar test comes back with 75ms in game mode. Now the argument is it's not as accurate for Plasmas. There could be upwards of a single frame or 16ms variance. So at best you're looking at 60ms. HDTVtest used the old tried and true camera method and they recorded results between 47 and 62. This fits in with the 16ms variance from the Leo Bodnar theory.
Trust me, I WANT the ST60 to be a great gaming TV. I have been stressing a TV purchase for weeks now. Every TV I find has some sort of flaw that makes me not want it. I just want the perfect TV under $1500 to come up and say hi. However as great as the ST60 picture is, I'll definitely be picking up a PS4 at some point and I want that experience to be as good as the TV watching.
But I see videos like this:

Compare that to the exact same test he does on the S60:

And I just can't bring myself to pull the trigger. Even the side by side Killzone video looks pretty rough to me for the ST60.
I know people will have different tolerances for the input lag and I think your suggestion of trying it out is really the best. I wish we had a store like the old Tweeter. I would bring a console into Tweeter and I have no doubt they would have let me hook it up to test before I bought a TV. I can't imagine Best Buy letting me do that.
I do like hearing that you haven't felt the input lag as being a problem. Unfortunately it makes me not want to rule out the ST60 and keep chewing on the decision though.. jerk
