Here's an answer from BEI. (the faxed quote was at $2,200+).  I guess we're still
some years away from real inexpensive solidstate gyros. Anybody know car make and
model these are likely installed in? Maybe need to pay a visit to the junkyard.

Dear Mr. Lassen:

The term "GyroChip" refers to a family of quartz rate sensors manufactured
by Systron Donner Inertial Division - SDID (all of SDID sensors share the
same technology; i.e., quartz not silicone).  Single axis sensors range from
the QRS11 (highest performance and most expensive) to the AQRS rate sensor.
Multi-axis sensors include the MotionPak and DQI packages.  SDID does not
sell the sensing element only.  All SDID rate sensors are complete; i.e.,
electronics are integral to the sensor.  The customer is only required to
provide a DC Input Voltage and the rate sensor output will be a DC analog
signal that is proportional to angular rate (angular velocity).  Integrating
the rate output will provide the customer with angle or angular
displacement.

To meet your unit price goals (<$100), may I suggest our AQRS rate sensor.
SDID provides this rate sensor to the automotive industry for an anti-skid
control system.  We currently manufacture 5,000 to 8,000 per day of the AQRS
rate sensor.  In small quantities of the AQRS-00075-109 rate sensor (1 to 3
units) the unit price is $300; when purchased in quantities of greater than
1,501 sensors, the AQRS-00075-109 unit price is slightly below $100.

If I can be of further assistance, please contact me directly.

Best regards,
