which 40-42 inch LCD to buy (within 90k)

[plank123]

I am planning to buy an LCD TV (40-42inches) and my budget is around Rs. 90,000.00. I have shortlisted the following -
1. Sony KLV-40W550A
2. Samsung LED UA40B6000VR
3. Samsung LCD LA40B650T1R
4. LG 42LH90QR

(any other models welcome .... no plasma's pls)

Please help in choosing 1 amongst the above 4.

My considerations are lowpower consumption, superb clarity (100Hz/200Hz), Long Life, and best picture clarity on my Airtel-DTH.

Thanks in advance!
