Reply to Best headphones for producing?

So I'm (probably) finally getting my act together and going away to school after a year and a half of not doing what I should be. Given where I'm going to be living--in a dorm or in a tiny apartment--I can't bring everything I'd like to with me. Specifically, I wont be able to bring the stereo I use with me that I use to produce the basslines in my tracks.

So really I need a pair of excellent headphones with great bass response. I don't want to say money is no object, but I know I'm looking at spending a couple hundred dollars.

(It's also worthwhile, though sad, to point out that I'll have to give up DJing for those months that I'm away at school )
