Ron,
It's a decent mic, I wouldn't necessarily rule it out if I were you, but understand what it is: it's an electret condenser mic with very low output. It has all the potential problems of a mic on stage - a condenser mic - including feedback. It sounds pretty good, but as I said, it definitely needs a preamp. I'd love to find the ideal solution, but there's no such thing. Everything is a compromise.
Best of luck.
Mike
