Anybody Own the latest 3DTV's? Specifically plasma.?

I am looking into getting panasonic's GT30, VT30 or ST30 as my 3d plasma TV for 2011. I heard that the glasses cause headaches and flicker etc. But I also heard this years models have glasses that work better to eliminate flicker or crossover ( especially on the plasma side) and that they don't cause headaches like the last year glasses did. Is this true and is this the year to grab a 3DTV?
