I used a Shure SM58 for a couple of years, and it was fine, although I had to turn the gain almost to full to get it to pick up my voice. I have since switched to a cheap(ish) lapel condenser microphone. The problem was not with the Shure, but with the mic stand I was using for it. I had a boom stand, and I found that no matter how I placed it, it blocked my view of the keys ... or the buttons, ... or cut across the display ... or I banged my hand against it when trying to turn the page. And since I have to move it to the Church and back every week, one less piece of kit was appealing.
