I saw the Onida model today. Its pretty good too, as well as the sound quality rocks.
If u r going for a subwoofer one, this is good.
Or else if u want to go for separate woofers then the Sony, Samsung or LG is better. I also saw a Philips Model whch had a better picture quality.
As for the subwoofers you can check out the ATP3 model(2.1 set) from Altec Lansing. It has got a decent sound quality.
