I'm willing to bet a new calibrated USB mic is more accurate as well then a radio shack old style one. specially used.
or just the app one may be enough for your purposes.
that said you can get professional quality ones form various places that supply the film-studio-recording industry. you may get one from an industrial safety equipment sales place as well.
