I have the CSS2123 soundbar. Bought it at Target for $79.99 new. It's the best small soundbar for the money in my opinion. Sound quality is solid, while not audiophile quality by any stretch it is decent for a small to medium room. The virtual surround is good too. It also has good selection of audio inputs (optical, coaxial digital, RCA, and a 3.5mm), as well as being compact and sleek. Way better than your TV's speakers.
Bass is probably the biggest downside. While not horrible, it could use a little more punch.
