LED TV help

[jjn]

I am planning to buy a LG LED LCD TV and I have shortlisted LG 32LE5500 and LG 32LE7500.
I am confused with the terms Infinia, LED plus. I understand from reviews that a backlit LED with localdimming is a better choice. Is LE7500 a edgelit or a backlit one ? The price difference is almost 8K. Not sure if it is worth. Request someone who owns this to give the feedback and advice me the best one between the two -Thanks!

I think the only adavantage of the LE7500 is the INFINIA design and nothing else.
Infact it's the LED5500 at a price lesser by 8k has two advatages over LE7500-backlit and the surround system.
