Tony, most manufacturers seem to be using "LED TV" for any TV that employes LEDs in any way shape or form for backlighting. Most manufacturers do not have now, nor have ever had local-dimming models available.

I picked up a Vizio local dimming 55" model in the XVT series, their highest at the time, just before they added internet bullshit to them, in Spring 2010 and I love it. It blows away any current thin Samsung models with edge-lit backlighting. Sure, it's a lot thicker at over 10cm, but it's hidden behind a panel anyway and not a single source component or wire is visible in my install either.
