Good music speakers for computer/ ipod?

I am looking to buy good speakers for music listening. I do watch movies and play games but those are not important. Strength, accuracy, balance are pretty important. I heard the M-Audio Studiophile AV 40's were pretty good. I have also heard a good amount about the Altec Lansing MX6021 2.1 Expressionist Ultra Speaker Systems. The AV 40's were mentioned more and have better reviews but do not have a subwoofer. Overall which one is better or does anyone have any recommendations on good speakers for the 200$ and under range. I also hear that BOSE is overpriced and not worth it.
