I think that little tester is probably a pretty good deal. I just have had all the equipment, the scopes, meters, signal generators and what-not since the 1970's, so I'm comfortable using them. Oscilloscopes and meters aren't really all that great for acoustic measurements, but they're good for electrical measurements. They're really all you need to measure electro-mechanical parameters.

You can measure Vas using a sealed box or added mass. You won't need a box for the added mass method. I used to approximate compliance with another method, but both the sealed box and added mass measurements are more accurate.
