We have the 55" on display at my store. Good bang for your buck, but aside from their design I don't find the picture to be all that great. I'm assuming it's using an LG panel since it uses FPR, but the passive 3D looked worse to me than it does on the the LW5600. A fair amount of ghosting and crosstalk. Also, just to clarify, this an LED edge-lit set with local dimming; it's not backlit.
