Maybe my money would be better spent on a good compressor for vocals.
Best I've ever used on vocals:
DBX 160A Actually I use the older 160XT, but they're basically the same.
Good mics will help you more than anything, and good doesn't mean expensive or popular. My favorite mic on bass and baritone vocals is a cheap MXL-V63M. The most popular mic MXL made was probably the V67, and in my opinion it was a dog. I couldn't wait to sell mine. Just remember that 95% of what you read in forums is nonsense. Just try out some different equipment and make your own judgments.
Something else that's gotten a lot praise are ribbon mics. I gotta tell you, I'm not a fan of them in general. They're great for stage work, mic'ing a sound-stage at a play etc. because they have this great ability to still sound full and clear at a distance of several feet--something a condenser mic just can't do, but for up close recording like we mostly do with instruments and vocals, I'll take a condenser every time. This is my old RCA BK11 mic. Some say it was the best ribbon mic ever made. I sold it to some steel guitar player in Switzerland for over a thousand bucks. It was an okay mic, but outside of a stage, I had no use for it. I don't miss it at all. Expensive doesn't mean good. But you already knew that.
