The new Shure SRH840s are probably about as good as you're going in to get in your price range. They run about $200, but according to Carl Seibert, you can get them at headphone solutions for $159.00 with a code. The Sony V6 is an old stand-by I like, though other people don't like it much at all. It's cheap, at least.
I had the Equation RP22X, which is supposedly the bass-heavier version of the RP21. It's an okay headphone for the money, but heavy. They also made my ears sweaty after a short period, which I'd never had before. I don't know about other. I heard the 840s at CanJam, though they were decent, but congested (as are almost all closed headphones).
On HF, you said in one thread you were 17 and could only pay cash. Is this true? This limits your options and ability to get deals on prices. If so, I'd think that would limit you to what's available in stores near you.
