I am not Sticking to Samsung. I too had similar choices to go for when we bought it two months back.Sony was good, but I didn't like its looks then. LG models are fine too and the subwoofer one is in par with an ONIDA equivalent.
But one thing I noticed with an Onida set in my neigbourhood, is that it tends to loose its sound quality over age- it doesn't have a 2500 watt subwoofer.

And regarding the subwoofers, you can figure out that the Subwoofers in most new models is just external; i.e, its fitted to the top of it, which can be removed easily(I don't know about ONIDA). When you consider a model with the subwoofer and a model without it, the price difference comes to be around Rs. 3000-5000. Now at that price I would prefer to opt for separate subwoofer set like an Altec Lansing or Creative, as the Sound quality would be much better.
