Do not get plasma if you plan to play games with a static HUD for hours at a time.
Plasma's still have not gotten past the burn-in issue. They have improved, but not gotten rid of it.
and you want the 100/120hz version. Otherwise when 3-D comes out, you will have to buy a new one.

Is it sure that if you want watch or play in 3D, you need at least a TV with 100 Hertz?
