Hi Jerry,

Geospace in Huston sells exploration geophones

you can also find something in China from Senshe

Sercel (also in texas) sells geophones.

In holland there is the I/O company that manufacture geophones.
I think they can sell you some samples.

costs for samples are usually around 100-200 $ per item 4.5Hz
and 200-400 $ for 2Hz sensors.

MEMS accelerometer still tobe not sensitive enough for weak motions.
