I know a lot of you use the Shadio Rack SPL meter, but has anyone any experience with the Cen-Tech meter? I got a catalog from AcousticSounds where they advertise that one for $39.95. They also list an ATI spl meter for the same price....
Check it out at SoundAcoustics.

By the looks of it, it comes from the same factory as the RS meter...

Yeah Mark, the meters may come from the same supplier. One thing that makes me wonder about them is offering the "Exorcist System Demagnetizer" as another useful item.
