Well, I've gone from the microphone in my Sony HandyCan to the microphones in my somewhat recently purchased ZOOM Q3HD. Then I moved over to computer recording. Yes, I'm a newbie. I was originally going with my Peavey PVM580TN but did a test of my Shure PL91A and I like it a little better. Less sensitive. So I did half a track and messed with it in Audacity and, well, I think I can pass as a less than fair vocalist. So that's where I am now, thinking about microphones. Do they REALLY matter? I did a Google Search and found the following:

(I haven't seen them yet, but will later today).

Frankly, although I'd like to read about different microphones being used and how much some like them, I think I have my heart already set on the Shure 55SH. The type of music I like playing is 50ish type stuff with a rock edge so I'm thinking the Shure 55SH might be ideal.
