Best Condensor Mic for the money\

What's the best condenser microphone for the money? I have a 4 track audio interface up and running. I have 3 tracks for instruments and I'm leaving one open for vocals, but a condenser mic can record anything that can't plug directly into the interface.
From your experience, what's the best one for the money? It can be any price rang. I just need some advice. Let me know, please.
