A less expensive data acquisition system is an Arduino with some simple interface wiring.
Cost around 25 euro.

To get below 1 ms I would probably connect a piezo film to an Arduino or something like that.

An Arduino does indeed have a low polling interval at the ADCs (I believe it is  around 100 µs). But depending on what kind of auditory feedback you want to give to the participant, 8bit beep sounds may not be very pleasant. 

Personally I would just stay in the analog domain and generate the sounds by one of these analog drum modules. They are inexpensive and can be triggered directly from piezo sensors (e.g.: http://www.mfberlin.de/Produkte/Module/DRUM-05/DRUM-05e/drum-05e.html)
