Well there are many brands available in the market so you could look around and check out demos. I have seen soundbars from Intex, Philips, Sony, Panasonic. If you have someone coming from US or can get shipping from US then you could get the COBY 90, JBL, Sharp, Insignia, Vizio, RCA and so on.
In India the prices start from around 5 odd thousand and go up to 25k while the US prices would start at around 3500 onwards. If buying from US do check if the speaker supports 240v power or you might need to get a converter.
