The Quake Catcher Network (QCN) has a low cost sensor.
 http://qcn.stanford.edu/

I think they are interested in the general earthquake education area rather
than generating early-warnings.

The sensor is USB, 3 axis.  They are selling them one-off for $50.  I don't 
know what they would charge for a batch and/or what they would cost for a 
large production run.

It comes with a small compass glued on the top.  Their installation 
directions request that it be oriented correctly and bolted down.  Big quakes 
are ballpark of 1G ground motion so it helps if the sensor doesn't get 
bounced around.  (I wonder how many internet connections would survive a big 
quake.  I don't care if your display gets trashed.  Does your router/modem 
survive?)

I think their software will run off the accelerometers built into some
laptops.
