Ultrasone, Beyer 770 or 880, ATHM50
If you want to spend less than $200 a pair than don't post that you can spend so much. Monitoring and headphones should be the last place you cut corners.
There is a significant difference in comfort and tonal quality between the $100 and less crowd and the $150-$200 + crowd of cans. Whether or not you can live with that difference is going to be up to you, your wallet, and your ears.
My best advice go try out a bunch of headphones at a nearby music store like a Guitar Center. If that's not an option than research online and pick what YOU feel best suits YOUR needs. Avoid buying blind though.
Two things are infinite: the universe and human stupidity; and I'm not sure about the the universe.
