Actually the LED is an LCD with a different lamp and uses less power.  
It's really misleading to call them something other than a LCD but the 
manufacturers chose to name the sets with the LED lamp as LED displays 
to set them apart.  I would choose an LED over the standard LCD due to 
using less power. they have a good reputation.
We have a 3 year old Samsung 40" and I'd not hesitate to purchase 
another. The only issue was one of those RoHS solder joints

Find an outlet store that will let you try sets out.  The local Best Buy 
let me take the set home and told me I could try as many as I wanted 
until I was satisfied.

Plasmas have improved but they are heavier and use more power than 
either the LCD or LED sets.

I'd have to be really hard pressed to purchase any Sony products. I 
haven't forgotten the rootkit and their CEO's remarks about the 
intelligence of their customers.
