I'd also suggest that you not write off Soundbars as gimmicks, especially when you plan to use them instead of a 2.1 system for the TV.
I listened to a few soundbar systems the last month. I wanted to separate my movie sound from my music setup, and I definitely didn't want any more speakers to be placed, or wires snaking across the room. I listened to quite few sets, right from 15K to 80K.
I actually bought two that I liked: a Yamaha YAS 105 (soundbar only; 25K) for my sister, and a Polk Surroundbar 9500BT (soundbar + wireless subwoofer system; 75K) for myself. The Yamaha YAS 105 is actually outstanding value for money, and I was very tempted to go for one of their their YSP Sound Projectors instead of the Polk 9500BT, but I didn't want to drop that much money on a movies only system. I don't regret that now, as the 9500BT gives an immersive virtual surround experience in my room (though not as good as the YSP), and the subwoofer in that system is very good.
The Q Acoustics M4 that senthildent mentioned above is also a very good soundbar in that range.
anitasudip, JBL has a soundbar + wireless subwoofer system at 15K, the SB150. It sounds good enough for the money and the convenience, to be considered over most 2.1 systems meant for use with computers. The Subwoofer of the JBL SB150 is slim and tall and you'll only need to manage a power cord, as the signal goes in wirelessly. I suggest that you try and listen to it if possible.
The JBL SB250 (again with a subwoofer) is also good, but in that range, I preferred a Yamaha YAS 105 by a large margin, even though it comes without a subwoofer (but has a subwoofer out for future expansion).
Please also consider how you will be giving output to the speakers from the TV. Most TVs these days don't have a 3.5mm or RCA analog outputs. They only have digital optical outputs. Most 2.1 systems will not take digital inputs. But most soundbars will have digital optical inputs (and analog inputs, of course).
