Jack,
A fellow using the handle "sazequip" has been selling geophones on ebay =
for
many months. His supply consists of 28-Hz vert and 4.5-Hz horiz. He's =
been
selling in lots of three, strings of 6 or 12 and multiple strings (just
recently he unsuccessfully tried to sell 10-strings of 12-sensors each). =
You
should consider dropping him a note from within ebay. Also if you do a
search on his name for "completed items" you can see what he has been
offering. Unfortunately the 28-Hz vert units are probably too high a
frequency to be useful in EQ monitoring.
Regards,
-Tim-

display board on Ebay for $26+$8, but I was holding out for even less. =20
I was interested in 8 or so.  I think All Electronics used to have
some but they're not in their catalog anymore.
