Studio Projects C3. They want you to go to B.L.U.E Baby bottle or Rode NTK- good choices, but *not* generally under $400. For just vocals, Studio Projects C1 (about $250), but for $100 more, still well under $400, you get muti-polar capability with C3. The hard part is no vocal mic sounds good on every singer. You could shell out for a C3 and find out your singer sounds better with an SM57! All you can do is get a bunch of mics and try them on the singer you got.-Richie
P.S.- one weird mic you would never expect sounds very good on quite a few singers- AKG D112, a $200 (give or take) dynamic kick drum and bass cab mic. I recommend buying one of these anyway, 'cause it's a real good bass and kick mic, but make a point of trying it on your singer just for the hell of it. It really works well on some people.-Richie
