In that price range, whatever you get should be good (it had
better be, anyway).
Also, whatever you get, try the different tips. I didn't think I'd like the foamies, but aside from the fact that they need to be cleaned/replaced from time to time, they work for me. Flanged tips seem to isolate well for me, but they seem weirdly intrusive. The soft silicone tips are comfortable, and seem to work well for some people. As Head-Fi members say, YMMV (your mileage may vary). Experiment to see what
you like. Again, at that price, you should do well.
You might want to consider the Shure E4's (if you were considering the E3C's, which I have), or maybe Westone UM2's (maybe neither is in your price range, but check around online -- and don't forget the Head-Fi sponsors). At the price level below $200, research Etymotics ER6i's, the Shure E3C's and the Westone UM1's. And of course there are 'phones from Ultimate Ears, and others as well, in a variety of price ranges.
You might do well to go for the $200 - $299 range right away, just to avoid the inevitable upgrade-itis for a while (I got Etymotics ER6's and Shure E3C's within the same year, but think what I could have gotten if I had just gotten one with the combined money I spent). Oh, and my condolences about your wallet ...
