BeyerDynamic DT770 Premium (600 ohm ver.) are my go-to cans for house, goa, and wubstep*; I got 'em new off of Amazon for a song ($185; I think prices are back up to $250 now) and amp 'em with a Practical Devices XM6 (that'll run you a pretty penny - a new one costs ~$400; the XM5 are just as good amp-wise and is in the $300 range if the XM6 is too rich for your blood).
Pretty much anything over $200, you're going to need a good amp to appreciate the full sound. My DT770s were pretty anemic on the bass when I was just powering them from an ASUS Xonar Essence ST; proper amping and I can actually feel a 48Hz wobble bass. :3
Also, excellent noise-cancelling and isolation. Probably too excellent, sometimes... I can't hear people coming up on me. (Great for using in a mildly noisy environment, though, if you want to block out the rest of the world.)
Oh yeah, and as far as "style" goes - the external shell is a nice matte black-and-silver. You can get Manufaktur'd cans straight from the BeyerDynamic site, but expect that to kick the price up by another $100 or so; me, I'd say just get someone who's good at arts and crafts and have them paint the shell over however you want. Since the DT770s are solidly closed cans, you won't adversely affect the sound signature with a coat of paint on the exterior. (If you somehow alter the structure, though... like, say, drill holes? That'll change things up, and probably for the worse.)
*: in fact, any time dubstep comes up from my foobar shuffle, I immediately switch over to my DT770s from my AKG K702s; the difference is profound.
