Radio Shack not knowing what a Sound Pressure Level is, that is crazy. As far as I know you can still get a digital and analog version?

Lets see if I can find it.................a quick search for "sound meter" on their website gives you the following.

It even says they are a Radio Shack exclusive item, I think I would ask to speak to the manager.
