STAY AWAY FROM MASSMARKET MAINSTREAM SPEAKERS
Stay away from the street brands of speakers you see in your local computer stores, if you want real quality, with the minimal number of bogus words with good connotations tied to pieces of underlying crap, go with semi-professional grade. For 200, you can find something really, really good.
I'd recommend the Swan M200, according to The Audio Insider, these can be purchased through NewEgg now. And the Swan M200 is a hybrid between a set of studio monitors and a set of computer speakers, they used to be as cheap as 199.99 US, but I haven't checked on the pricing lately.

I personally auditioned these at a local speaker dealer, they are constructed with semi-audiophile grade materials, huge binding posts, and very good quality cabinetry. The built-in amp sounded clean and resourceful, the music was natural and smooth with beautiful imaging to the extent that any other computer speakers i have heard can not match these.
