You can find Beyerdynamic DT-880 or DT-990 for under $200 (the pro version, not the premium version that frequently shows up on here for $240). Sounds good and very solidly built.
You can also get the Grado sr225e for $200 (or the 80 or 125 for less).
But it all depends on what you are looking for. If you can make it to a headphone meetup, you can have the chance to listen to a bunch of different headphones. Most of them are going to sound pretty good, but there are a lot of differences between brands
Also, with a lot of these headphones, you are going to need an Amp to fully power it (if you don't already have one), so count on at least another $50 - $100 for that.
