Since you are in hyderabad, Do visit the Ezone in Jubilee hills (Road number 36, Near Honda Showroom). They have a 2008 model LG 42PG21 in display.
This thing does not have "smart Energy Save" or whatever bullshit they introduced in 2009.
Actually I dont mind spending on electricity for that kind of picture. Suffice to say that it can go is as bright as a LCD which was nearby (Samsung 5 series). Even "Normal" mode looked brighter than vivid mode of 2009 models. LG has also listed it as "Ultra Bright Panel" in the product page (42PG61s too) which they removed in the 2009 models.
I have to say the picture looks great with good amount of brightness.
From here, I can equate what I will miss in terms of brightness from 2009 models.
Man, the PV8 and PV80 would have looked wonderful compared to C10 & X10. If only I was shopping last year..
I could not get the demo of a PV8/PV80 anywhere. Guys in hyderabad, please let me know if you come accross tham anywhere.
Iam even thinking of picking up one of these if it is available anywhere.
P.S: You can see PQ70 in the croma next door within 5 minutes. So the brightness factor is not subjective but objective.
