The meter from Radio Shack is the one I own as well. This is not a precision instrument, but can hardly be faulted considering the low selling price. I doubt that there is much difference in accuracy of the two models (digital / analog) The "slow" mode (where the viewer may easily follow the analog meter swing) is as easily interpreted as the lights on the digital model. With either one of these, the main use would be to test SPL in an automobile, surround sound levels balancing, and tests for ambient sound pressure levels to insure safety with long term exposure to work noise levels. For all these things, it is a great inexpensive tool.
