Hi Dome,

I got tired of the gain issue with my EMU interface and my SM58 and bought a Gauge ECM-87 and I love it. Great sound. Low noise. Requires phantom power. $149 comes with case and pop screen.

Also a couple of people on here use the Blue Yeti which is a USB mic and sounds great.

Good luck in your search.
