Dear Alastair,

I've posted quite a bit of information related to making a seismometer on
this page:

I'll also forward your question to the Public Seismic Network E-mail list,
as some members may have a lead on an inexpensive, used geophone.

For high frequency demonstration purposes, it may be possible to dangle
a strong magnet inside a home wound coil to make your own sensor.

Good luck,
