Default EdgeLit LED or Backlit LED or Backlit w/local dimming LED

I've been doing some research on the LED because I'm in the market for a new TV. Here a quick pros and cons of what I found with these technology and was wondering what do you guys think?

Edgelit:
Pros: Thin and great colors.
Cons: LEDs are on the edge not giving a uniform light source

Backlit:
Pro: Great colors and uniform light source accross screen
Con: Same as CCFL light system

Backlit w/local dimming:
Pro: Great colors, better blacks and whites
Con: Creats blooming effect

So which ones would be better or which one would you perfer?

From the research I've done I leaning towards the regular Backlit. Yes it doesn't give a true black but at least the light source is correct through out the complete picture. I've been really looking forward to local dimming but the blooming effect of whites on blacks can really decrease detail and at times give a halo effect. What do you guys think?

What about a plasma TV with 120hz to produce a true 24p picture? Yes I know I haven't been able to find one or more like they don't make any.

What price range are you looking at?

Panasonic and Samsung have released 96 Hz plasma TV's that properly use 4:4 for 24p sources. The Panasonic V10 series is currently CNET's top HDTV, followed by the IIRC Samsung 860 series. These do not suffer from the cons of the LCD TV's you described above.

I'm not looking at spending to much. In the price range of 2000-3000 for a 46 inch. 46 in screen because the distance from where I sit to the TV a 46 is best.

That's a pretty nice budget for a 46" screen. If you're comfortable with 50" the Panasonic TC-P50V10 is under $2000, and like I said before it's CNET's top HDTV this year.

There is a very good comparison of local-dimming and edge-lit LCD in this month's Sound and Vision. My understanding is that edge lit is bright with excellent color sat, but may suffer some of the problems that CFLs suffer, namely greyish blacks. I've viewed a couple of edge lit LCDs and felt that the achieved excellent blacks when compared to my bedroom set, which is a 46" LG.

As to local-dimming, the standard white LED sets suffer from blooming problems wherein the LED causes a halo when lit if other nearby LEDs are off. That said, the Sony locally dimmed sets use four LEDs per locale - red,green,blue and white. I've seen these sets in action and thought that the contrast was as good as my 58" THX Panny plama and the color saturation probably exceeded it. However, it was roughly $5k for a 52" screen.

My two cents is that, for the money, Plasma offers a more accurate film experience.

From what I have read about LED-TVs the Sony X4500 (XBR8 in US) has still best picture. It's backlit with local dimming and RGB LEDs.

It has amazingly accurate color reproduction (think Pioneer Kuro, almost) but does not achieve the total/0 nits black of TVs with local dimming white LEDs. Its price was ridiculous last time I checked though (~3500 euros for the 46 inch model).

You can have it now for about 2500€ in EU, probably cheaper if you order it from Germany for example.
