Get away from the Wesc crap.
You could do a lot worse than the Shure 440 or 750DJ, and the 750s sometimes go on sale for less than $150.
If you can stretch your money just a bit, you can take a look at some Beyerdynamic DT770/Pro 80 at pro audio stores. For about $180, you can get truly world-class bass.
That much can also put you into some decent Ultrasones, which should sound pretty solid--maybe the Ozma 5 @ $100 that sell out of Brampton on ebay.
The M-Audio Studiophile is right around $150 too, and is supposed to have an ideal sound for the music you're looking for. (Moog Audio carries them)
Senn HD-25 SP are also that price, if you're looking for something smaller.
