for in-studio realtime use, in the ~100 dollar range will get you a nice pair of sony headphones. there are so many models out there that it's tough to pick just one out. i would recommend you run over to http://www.audioreview.com and see what they have to say about various models. grado makes a great sounding pair of phones for about 60 (the SRM-60s, are they?), but they're an open design, and as such, typically not a good match for studio work. sony makes the best closed phones in your pricerange, by most accounts..
check thsi auction out on ebay. This guy has a few Sony MDR 7506 headphones for $80 +shipping with full warrenty. I guess there slightly used but in great condition.
This auction is closed but just email him because he has plenty more.
I've heard some great things said about the Grado headphones - their low-end stuff starts in this range (75 or so) - also, the Senns are always nice - check out the Headroom at www.headphone.com for more info
the 7506's are held in very high regard for a decent, well-isolated closed set of studio phones. they're designed for at least moderate monitoring work in fairly noisy environments. you might have better casual listening with something else, but it's hard to go too wrong with these.

I have four sets and can recommend them. I wouldn't be inclined to use them for mixing as they have a slightly 'smiley face' response but they are plenty loud enough. The bottom end is not as ridiculously boomy as seems to be the fashion these days.
