Yeah, there is a Sennheisser in your budget... like a 930 or something? I'm personally fond of the Beyer M-88, the Beyer M-69 is cool, too. You might look into one of the low budget chinese condensers... I don't know what is cheap over there, here a Studio Projects C-1 would be an inexpensive option. For a few bucks more, the Neumann 105 ain't too bad. AT makes several mics in the 40nn series that are similarly priced. The long and short of it is that there are quite a few mics out there.
My own recomendation would be for you to use what you have, and for you to save a little more to get a much better mic. What happens is that as you get more experience, you'll want better quality. In the case of microphones, it is easy to wait a while, save a few bucks and buy a better one, and then have a great mic that you will use for the rest of your life.
